Mitigating Cracking in COP Optics through Annealing and Step-Torquing2026-26-07646/1/2026
Polymeric optical materials such as Cyclo Olefin Polymer (COP) are adopted in aerospace lighting systems due to their excellent optical clarity, dimensional stability, moldability and weight saving advantages over glass. However, their relatively low toughness and the presence of residual molding stress make them prone to crack initiation during mechanical fastening. During its installation, crack formation was consistently observed around self-tapping screw interfaces, raising concerns over reliability, maintainability, and compliance with durability requirements. A structured Design of Experiments (DOE) was performed to identify root causes and evaluate potential mitigation methods. The investigation revealed that residual stresses in the COP material, combined with localized stress concentrations during screw tightening, were the primary drivers of crack initiation. Two complementary process improvements were identified and validated as part of mitigation plan: (i) annealing of the

Optimizing Coil Structural Parameters to Enhance the Sensitivity of Wear Particle Sensor2026-01-50335/14/2026
If wear particles generated during the operation of automobile engines are not monitored in time, they will contaminate the lubricating oil, leading to system failures or even accidents. Therefore, real-time wear particle monitoring is crucial for the stable operation of engines. Among mainstream wear particle monitoring sensors, the three-coil inductive sensor demonstrates significant application potential due to its ability to distinguish wear particle materials and strong resistance to environmental interference. However, its insufficient sensitivity to small-diameter wear particles limits further performance improvement. This paper takes the three-coil inductive wear particle monitoring sensor as the research object. First, a mathematical model of the sensor’s operation is established based on the law of electromagnetic induction, clarifying the relationship between structural parameters (such as channel radius, turns, coil spacing, and length) and the peak induced voltage

Hydrogen Embrittlement in Galvanized High Carbon Steel Components of Automotive Seat Slider Assembly2026-26-03021/16/2026
This research paper investigates the failure of an isolator clip used in the seat slider assembly, which guides and restricts the sliding motion of the tooth bracket within the seat. The component is made of C80 high-carbon spring steel, known for its high strength. According to the manufacturing process details, zinc plating was applied to the component for corrosion protection, as confirmed by EDS analysis. A fractographic examination of the failed part revealed a brittle, intergranular fracture morphology with visible cracks. Certain areas also exhibited micro-void coalescence, indicating a dimpled fracture surface. The primary failure mode was intergranular (IG) fracture. The delayed fracture was attributed to intergranular fracture mechanisms, micro-void coalescence, and the high strength of the steel, which made the component susceptible to hydrogen embrittlement. Hydrogen embrittlement occurs when hydrogen atoms become trapped along the grain boundaries, where they form hydrogen

Hypoid Gear Performance Redefined: Addressing Scoring & Whine Noise Concerns2026-26-00781/16/2026
Rear drive vehicles transfer power to the rear wheels through the Gear Carrier Assembly, which is fit at the central section of the Rear Axle. The Gear Carrier Assembly includes hypoid ring and pinion gears, set at the heart of the system. However, one of the common issues with hypoid gears is gear scoring and whine noise, both of which can seriously affect durability and reduce the overall performance of a vehicle. In this study, the focus is on design changes as well as process improvements to address these problems and at the same time improve gear reliability. On the design side, changes such as refining the macro geometry, upgrading materials, and modifying the heat treatment cycle were carried out. These helped in improving properties like contact stress resistance, bending and impact strength, and also reduced motion transmission error (MTE). From the process point of view, careful control over carburizing, hardening, and quenching temperatures, along with adjustments in

Non-Metallic Inclusions in Carburizing Steels as a Contributory Factor for the Formation of Carbide Net2026-26-02901/16/2026
The article deals with the issue of identifying structural defects that contribute to the formation of a carbide net during thermochemical treatment of steel parts, which negatively affects the mechanical properties complex of finished products. Based on the available data, a theory has been put forward regarding the influence of the present non-metallic inclusions in the carburizing steels structure on carbide formation process in the hardened layer. As an experimentally the samples have been produced from the varying chemical composition alloy structure carburized steel (0.17-0.23 % C, 0.17-0.37 % Si, 0.80-1.10 % Mn, 1.00-1.30 % Cr, 0.03-0.09 % Ti). During microstructure analysis of the samples it has been establish that non-metallic inclusions, in particular sulfides, contribute to the formation of carbides and carbide net in steel due to their high chemical activity with carbon. Thus, contamination of the metal of carburizing steels with non-metallic inclusions is not only a defect

Advancing Welding Excellence Through Numerical Simulation Based Approach: A Multi Pass Welding Case Study on Cast Iron Coupons2026-26-04571/16/2026
The Automotive industry widely uses cast iron due to its better mechanical performance and cost-effectiveness. However, repair welding or assembly of cast iron components remain highly challenging due to the material’s high carbon content, inherent brittleness, rapid thermal conductivity, and complex microstructural transformations. Multi-pass welding exacerbates these challenges by subjecting materials to repeated thermal cycling, accumulating residual stress, and inducing distortion – all of which potentially degrade the integrity of welded joints. A comprehensive understanding of welded joint behavior is essential to effectively mitigate these effects. Finite element analysis (FEA) serves as a powerful tool, enabling accurate prediction of thermal profiles, phase transformations, residual stress development, and resulting deformations. These valuable insights are critical for optimizing welding processes and enhancing overall joint quality. This study investigates and validates the

Advancement in Analytical Characterization of NBR: Py-GC-MS as an Alternative to NMR for Acrylonitrile Quantification2026-26-05461/16/2026
Nitrile Butadiene Rubber (NBR), known for its superior resistance to hydrocarbon oil, low gas permeability, and excellent thermal stability, finds extensive use in seals, O-rings, conveyor belts etc. Importantly, these performance attributes are chiefly governed by acrylonitrile content in NBR. Analytical characterization of raw NBR is relatively straightforward using conventional techniques such as elemental analysis (CHNS) and liquid state 13C NMR. In contrast, the analysis of vulcanized NBR presents considerable challenges due to its crosslinked structure, which renders it insoluble in most organic and inorganic solvents, thereby restricting direct molecular-level analysis. While solid-state 13C NMR is an established technique for structural characterization in rubber vulcanizates, its high-cost curbs routine industrial analysis. In this study, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GC-MS) technique has been explored as a robust, precise, cost-effective alternative

Development of a Localized Heat Treatment Route for Stamped Automotive Parts2025-36-008912/18/2025
The increasing demand for sustainable and space-efficient manufacturing solutions in the automotive industry has driven the search for alternative processes to conventional hot stamping. This study proposes a novel localized heat treatment technique based on Joule heating, aiming to reduce the physical footprint of production equipment, simplify the thermal processing of structural components, and minimize the carbon footprint of the process. The method consists of cold stamping followed by localized austenitization of 22MnB5 steel using electrically powered copper electrodes, eliminating the need for large-scale gas-fired furnaces. The process is particularly advantageous in the Brazilian context, where the electric energy matrix is predominantly hydroelectric, contributing to lower CO2 emissions. Experimental trials were conducted using a Gleeble® thermomechanical simulator to optimize thermal cycle parameters (heating rate, austenitization temperature, and soaking time) ensuring the

In order to improve the operational efficiency of a multi-runway airport, an aircraft pushback and taxiing cooperative departure operation control method is proposed. First, a Markov decision process (MDP) model for dynamic pushback control is established based on the two-runway model. Then, the genetic simulated annealing algorithm is used as the optimization algorithm, and the DPC-GSAA algorithm solution model is proposed to find the conflict-free path with the least fuel consumption for the aircraft and runway selection. Finally, the effectiveness of the model and algorithm is verified by simulation experiments in Beijing International Airport, and the results show that the method can significantly reduce the taxiing waiting time of aircraft and improve the overall operational efficiency of the airport.

Evaluating the Influence of Material Properties and Hardness on Tightening Torque2025-28-025511/6/2025
Earthmoving machines are equipped with a variety of ground-engaging tools that are joined by bolted connections to improve serviceability. These tools are made from heat-treated materials to enhance their wear resistance. Attachments on earthmoving machines, including buckets, blades, rippers, augers, and grapples, are specifically designed for tasks such as digging, grading, lifting, and breaking. These attachments feature ground-engaging tools (GET), such as cutting bits or teeth, to protect the shovel and other earthmoving implements from wear. Torquing hardened plates of bolted joint components is essential to ensure uniform load distribution and prevent premature failure. Therefore, selecting the proper torque is an important parameter. This study focuses on analyzing various parameters that impact the final torque on the hardened surface, which will help to understand the torque required for specific joints. Several other parameters considered in this study include hardware

Higher-Strength, Higher-Toughness Die Cast Wheel Material using Recycled Aluminum2025-32-000711/3/2025
In an attempt to reduce CO2 release from alloy wheel production, we have developed an aluminum alloy for casting that satisfies necessary property requirements using recycled aluminum, but without heat treatment. The wheel is a critical safety feature of any vehicle, and it should have toughness and strength .In many wheels, virgin aluminum containing small amounts of impurities is used to maintain toughness, and heat treatment (T6), which is post-casting quick heating and quenching, is applied to provide strength. At the start of this project, we focused on two wheel-manufacturing processes, production of virgin aluminum and heat treatment, from which a large amount of CO2 is released. By switching to recycled aluminum, CO2 was reduced to one-ninth the original amount. The issue with recycled material is that impurities grow in the metal structures as intermetallic compounds and this reduces toughness. To deal with this issue, we have chosen high-pressure die casting (HPDC), in which

Investigation of the Effect of Rotation Speed and Post-Weld Heat Treatment on Mechanical Properties and Structure of Friction Stir Welding AA6061 Joints05-19-02-00169/25/2025
This study aims at examining the effect of tool rotational speed on the microstructural and mechanical properties of friction stir welded joints of AA6061 aluminum alloy, both pre- and post-heat treatment. The quality of the joints was assessed initially through tensile, hardness, and charpy impact tests, as well as microscopic observations. During the second stage, solid solution heat treatments were conducted at 535°C, followed by aging on additional specimens welded at identical speeds. The latter underwent hardness tensile tests and microscopic examinations. A comprehensive assessment of the outcomes from various tests validated the influence of metallurgical phenomena, including recrystallization, precipitation, and structural defects on overall resistance. The results showed an improvement in strength, ductility, and impact energy was observed in the case of welding at high rotation speed (1400 rpm). At the same speed, ductility almost doubled after post-weld heat treatment
