Lightweight Magnesium Nanocomposites with Enhanced Wear Resistance for Landing Gear Application2026-26-07516/1/2026
This study systematically evaluated the wear resilient performance of AZ61 magnesium alloy reinforced with 15 wt.% SiC and diverse amounts of multi-walled carbon nanotubes (MWCNTs) under dry sliding circumstances adopting pin-on-disc apparatus (ASTM G99). To identify the influence of factors like sliding speed (SS) (1-3 m/s), axial load (AL) (10-30 N), and MWCNT concentration (0-3 wt.%) that affect tribological performance, experiments were developed using a Central Composite Design (CCD) under Response Surface Methodology (RSM). SEM micrographs revealed a dispersion optimum near 2 wt.% MWCNT, where CNTs anchor to SiC and bridge the α-Mg matrix, while 3 wt.% shows agglomerates and micro-voids. Findings showed that wear loss (WL) and friction coefficient (CoF) was greatly amplified by increasing AL owing to localized heating and contact stresses. A compacted tribolayer was formed by increasing SS, which decreased WL but marginally raised the CoF. At low AL (10 N), SS (2.09 m/s), and 2.12 wt.% MWCNT, the wear resistance was significantly improved by improving load transfer and creating a lubricating carbon-rich coating, resulting in a decreased WL of 0.006 g. The CoF persisted within the range of 0.19 to 0.28. Agglomeration of MWCNTs caused increased WL and CoF when the MWCNT content is increased above 2 wt.%. Worn-surface microscopy at the optimum showed fine wear tracks and a continuous carbon/oxide glaze, evidencing a lubricious CNT-rich third-body film, whereas high AL/low MWCNT produced deep grooves and delamination.

Stir Casting Synthesis and Evaluation of SiC Nanoparticle-Reinforced AZ31 Magnesium Alloy Nanocomposites2025-01-50133/10/2025
In an attempt to improve its mechanical characteristics in the as-fasted conditions, the AZ31 Mg alloy was investigated herein from being reinforced with diverse SiC weight percentages (3, 6, and 9 wt.%). To develop lightweight AZ31-SiC composites, a simple and inexpensive technique, the stir casting process, was used. Microstructural analysis of the as-cast samples showed that the SiC particles were distributed rather uniformly, were firmly bonded to the matrix, and had very little porosity. The substantial improvement in tensile, compressive, and hardness characteristics was caused by fragmentation and spreading of the Mg17Al12 phase, while the addition of SiC had only a slight effect on the microstructure in the as-cast state. Surfaces of AZ31-SiC composites were analyzed using scanning electron microscopy. A study identified the AZ31-SiC composite as a unique material for applications involving a high compressive strength, such as those found in the aviation and automobile engineering fields.

Synthesis and Machining Characteristics Evaluation of Silicon Nitride Made Magnesium Alloy Composites05-18-03-00171/20/2025
The advantages of magnesium alloy composites over traditional engineering materials include their high strength and lightweight for automotive applications. The proposed work is to compose the AZ61 alloy composite configured with 0–12% silicon nitride (Si3N4) via semisolid-state stir processing assisted with a (sulfur hexafluoride—SF6) inert environment. The prepared AZ61 alloy and AZ61/4% Si3N4, AZ61/8% Si3N4, and AZ61/12% Si3N4 are machined by electrical discharge machining (EDM) under varied source parameters such as pulse On/Off (Ton/Toff) time (100–115/30–45 μs), and composition of composite. The impact of EDM source parameters on metal removal rate (MRR) and surface roughness (Ra) is measured. For finding the optimum source for higher MRR and good surface quality of EDM surface, the ANOVA optimization tool with L16 design is executed and analyzed via a general linear model approach. With the influence of ANOVA, the Ton/Toff and composite composition found 95.42%/1.27% and 0.36% impact for MRR and 30.74%/21.01%/18.27% of Ton, Toff, and Ra. The optimum parameters for electrical discharge machining have been determined, and the composite material of AZ61/8% Si3N4 has been identified as having a favorable MRR/Ra value compared to other materials.

Characteristics of Magnesium Composite Reinforced with Silicon Carbide and Boron Nitride via Liquid Stir Processing2024-01-523712/10/2024
The present aim of the investigation is to prepare and evaluate the excellence of boron nitride (BN) and silicon carbide nanoparticles on characteristics of magnesium alloy (AZ91D) hybrid nanocomposite. This constitution of AZ91D alloy hybrid nanocomposite is made through the liquid state processing route, which helps to improve the spread of particles in the AZ91D matrix. The impact of BN and SiC on microstructural and mechanical properties like tensile strength, hardness, and impact strength of AZ91D alloy composites are studied, and its investigational results are compared. Besides, microstructural studies have revealed that the structure of composite is found to have better BN and SiC particle dispersion and uniformity. The 5 percentage in weight (wt%) of BN and 5 wt% of SiC facilitated better tensile strength (183 MPa), hardness (85HV), and impact strength (21.4J/mm2) behaviour, which are 26, 30, and 35% better than the monolithic AZ91D alloy. This AZ91D/5wt% BN and 5wt% SiC hybrid composite is involved in automotive top roof frame applications.

Magnesium Alloy Hybrid Composite Properties are Featured with Boron Carbide Particle for Automotive Seat Frame Usage2024-01-520712/10/2024
With the advancement of lightweight magnesium-based hybrid composites, are potential for weight management applications. The liquid state stir cast process is the best way to produce complex shapes and most industries are preferred. However, the melting of magnesium alloy and achieving homogenous particle distribution are the major challenges for the conventional stir-casting process, and hot crack formation is spotted due to thermal variations. The main objectives of the present research are to enhance the microstructural and mechanical behaviour of magnesium alloy hybrid nanocomposite (AZ91E) adopted with boron carbide (B4C) and alumina (Al2O3) nanoparticles through a semisolid stir cast technique associated with inert atmosphere helps to limits the oxide formation and reduce risk of magnesium fire. The effect of composite processing and multiple reinforcements on surface morphology, tensile strength, impact strength, and hardness were thoroughly evaluated and compared. The results of surface morphology studies demonstrate homogeneous particle dispersion with reduced casting defects. Furthermore, the AZ91E alloy hybrid nanocomposite (HNC) exhibits superior tensile strength, impact strength, and hardness when compared to the monolithic AZ91E alloy, showcasing improvements of 18%, 23%, and 25%, respectively, which is suggested for automotive seat frame applications.

Characterization of Graphene and Titanium Carbide Reinforced Magnesium Alloy Composite for Transmission Housings in Automobile2024-01-523112/10/2024
This study presents the mechanical characterization studies on 3 wt.% graphene (Gr) filled magnesium matrix composite reinforced with different weight fractions (4, 8, 12, 16, and 20 wt.%) of titanium carbide (TiC) particles. The matrix is AZ91 alloy, and the nano magnesium composite (NMC) is fabricated via a squeeze casting approach. The lightweight NMC is a potential solution for the automobile industry, as it reduces greenhouse gas emissions and contributes to environmental sustainability. Gr is added to enhance the composite's thermal endurance and mechanical strength. Mechanical and corrosion studies are performed as per the ASTM standards. The inclusion of Gr and 16 wt.% TiC tends to enhance the mechanical durability and corrosion resilience of the NMC when compared with other fabricated composites and cast alloys. The uniform dispersal of NC and TiC and better mould properties lead to better strength. Higher inclusion of TiC (20 wt.%) leads to brittleness, thereby decreasing the overall wear loss by resisting abrasive, which lowers the composite's flexibility and strength. The potential mechanism of adhesive wear is shown by the fact that TiC and Gr decrease the intimate contact region between the composite and the EN31 counter-disc. Compared with as-cast alloy, AZ91+3%Gr+16%TiC produced 64.31% higher porosity, 19.50%, 26.69%, 59.45%, and 19.66% higher UTS, micro-hardness, impact, and flexural strength.

Magnesium Alloy and Silicon Nitrides Composite Study: Synthesis and Abrasive Water Jet Machining Behavior and Optimization05-18-02-001411/15/2024
Related to traditional engineering materials, magnesium alloy-based composites have the potential for automobile applications and exhibit superior specific mechanical behavior. This study aims to synthesize the magnesium alloy (AZ61) composite configured with 0 wt%, 4 wt%, 8 wt%, and 12 wt% of silicon nitride micron particles, developed through a two-step stir-casting process under an argon environment. The synthesized cast AZ61 alloy matrix and its alloy embedded with 4 wt%, 8 wt%, and 12 wt% of Si3N4 are subjected to an abrasive water jet drilling/machining (AJWM) process under varied input sources such as the diameter of the drill (D), transverse speed rate (v), and composition of AZ61 composite sample. Influences of AJWM input sources on metal removal rate (MRR) and surface roughness (Ra) are calculated for identifying the optimum input source factors to attain the best output responses like maximum MRR and minimum Ra via analysis of variant (ANOVA) Taguchi route with L16 design approach. The ANOVA analysis revealed that D, v and the composition of AZ61 alloy composite contribute 26.45%, 16.28%, and 20.84%, respectively, to the output response conditions for higher MRR. Additionally, design 7 exhibits a high MRR of 0.017 g/s and a surface roughness (Ra) of 0.84 μm. The optimum AWJM input source of design 7 is proposed for industries to mass production applications.

Effect of Solutionising on Change in Phase Morphology, Mechanical Behavior & Corrosion Behavior for AZ Series as Cast Automotive Magnesium Alloy Components2022-28-005810/5/2022
Magnesium is sought to be one of the futuristic material in automotive due to its superior properties such as density, strength to weight ratio, damping characteristics and thus, making it a key enabler for light weighting. The properties of Magnesium alloys can be widely altered by change in elemental composition and heat treatment. Analysis of composition and phase morphology are driving factors for determining component’s end use properties and can be utilized effectively in its product development cycle. The as-cast AZ series alloys develop microstructure consisting of α-Mg matrix, eutectic α-Mg/γ-Mg17Al12 phase with non-uniform Al solute content in the α-Mg. Solutionising causes dissolution of Mg17Al12 brittle phase thereby increasing strength and ductility in these alloys. This paper presents analysis of AZ series automotive alloy components with focus on microstructure and mechanical properties change after solutionising. Scanning electron microscopy & energy dispersive spectroscopy techniques are adopted to evaluate phase changes along with morphology which affected properties after solutionising. Corrosion behaviour of AZ91 in as cast, solutionized and solutionized & aged condition is also studied.

Low-Cost Magnesium Alloy Sheet Component Development and Demonstration Project2022-01-02483/29/2022
Most of the applications of magnesium in lightweighting commercial cars and trucks are die castings rather than sheet metal, and automotive applications of magnesium sheet have typically been experimental or low-volume serial production. The overarching objective of this collaborative research project organized by the United States Automotive Materials Partnership (USAMP) was to develop new low-cost magnesium alloys, and demonstrate warm-stamping of magnesium sheet inner and outer door panels for a 2013 MY Ford Fusion at a fully accounted integrated component cost increase over conventional steel stamped components of no more than $2.50/lb. saved ($5.50/kg saved). The project demonstrated the computational design of new magnesium (Mg) alloys from atomistic levels, cast new experimental alloy ingots and explored thermomechanical rolling processes to produce thin Mg sheet of desired textures. A new commercial Mg alloy sheet material was sourced and pretreated with protective coil coatings, and its properties fully characterized. The Mg sheet was successfully warm-formed using novel lubricants into intermediate size benchmark parts and full-size automotive door inner and outer panels. The project also explored conventional welding processes for joining of Mg sheet, developed novel corrosion treatments for multi-metal assembly coatings, performed computer simulations of door panel forming using two new material cards based on crystal plasticity theory, and concluded with a door static and dynamic performance analysis. An overall cost driver and sensitivity assessment task compared the final cost penalty depending on the cost of the primary magnesium sheet.

Investigation of Hot Corrosion Behavior on QE22A-Magnesium Silver Alloy through Steaming Method05-15-03-00153/3/2022
The hot corrosion studies for the die-casted magnesium (Mg) silver (Ag) alloys are carried out through the steam heating route. The Magnesium Silver (QE22A) alloy is fixed under the top lid of the pressure cooker (2 liters) and filled with water and 5% salt (NaCl) solution. The specimens are treated with different time intervals (10, 20, and 30 minutes), with the steam temperature maintained at 100°C around the specimen. The results showed an increase in the corrosion rate with the increase in the steaming time. Further, after the specimens have cooled down to room temperature, similar experiments are repeated for the second and third cycles. Here the formation of the oxide layers over the specimen has reduced the corrosion rate. The structural, surface study was carried out through scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive spectroscopy (EDS) to know the corrosion behavior on the specimen. From the microstructure, it is noticed that the average grain size increased with the increase in the time intervals. Through SEM images, detailed studies on the crack length and pitting width were carried out. Finally, a comparison of pure and corroded alloys is made and discussed in detail.
