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

Microstructure, Tensile and Fracture Behaviors of Squeeze Cast Wrought Mg Alloy AZ80

2025-01-8230

04/01/2025

Wrought magnesium alloy AZ80 with a thick section of 20 mm was prepared by squeeze casting (SC) and permanent steel mold casting (PSMC). The porosity measurements of the SC and PSMC showed that the SC AZ80 had a porosity of 0.52%, which was the 77% lower than that (2.21%) of the PSMC counterpart. The microstructure analyses and phase identification indicated that the cast AZ80 alloy consisted of a primary α-Mg phase, eutectic Mg-Al-Zn phases and Al-Mn intermetallic. The fine primary α-Mg dendrites and a high amount of the intermetallic phase were present in the SC AZ80 alloy. The yield strength (YS), ultimate yield strength (UTS), elongation (ef), elastic modulus (E) and strain hardening rate of the cast AZ80 specimens were evaluated by tensile testing. The measured engineering stress versus strain curves showed that the SC AZ80 alloy exhibited 84.68 MPa in YS, 168.23 MPa in UTS, 5.07% in ef, and 25.1GPa in modulus while the YS, UTS and ef of the PSMC specimen were only 71.61 MPa

A New Methodology to Characterize the Influence of Paint Baking and Pre-Straining on the Tensile Properties of Third Generation Advanced High Strength Steels

2025-01-8223

04/01/2025

The current ASTM A653 standard for determining the bake hardening index (BHI) of sheet metals can lead to premature fracture at the transition radius of the tensile specimen in high strength steel grades. In this study, a new test procedure to characterize the BHI was developed and applied to 980 and 1180 MPa third generation advanced high strength steels (3G-AHSS). The so-called KS-1B methodology involves pre-straining over-sized tensile specimens followed by the extraction of an ASTM E8 sample, paint baking and re-testing to determine the BHI. Various pre-strain levels in the range of 2 to 10% were considered to evaluate the KS-1B procedure with select comparisons with the ASTM A653 methodology for pre-strain levels of 2 and 8%. Finally, to characterize the influence of paint baking at large strain levels, sheared edge conical hole expansion tests were conducted. The tensile mechanical properties of the 3G steels after paint baking were observed to be sensitive to the pre-strain with

Effect of Hardening and Tempering Temperatures on the Mechanical Behavior of Alloy Steel

2025-28-0027

02/07/2025

Alloy steel possesses high strength, hardenability, fatigue strength, and good impact toughness. It is widely used for making various machine parts, automobile components, shafts, gears, connecting rods, and more. Hardening and tempering develop the optimum combination of hardness, strength, and toughness in engineering steel, thereby providing components with high mechanical properties. Hardening and tempering temperatures are crucial factors that affect the mechanical and metallurgical properties of 42Cr4Mo steel. In this research work, 42Cr4Mo alloy steel samples were subjected to hardening and tempering processes. The hardening temperatures were set at 830°C, 850°C, and 870°C, while the tempering temperatures were maintained at 590°C and 650°C. The test results show that hardening at 830°C and tempering at 590°C achieve high tensile strength, which decreases as the temperature increases. Different hardening temperatures and constant tempering temperatures will be optimized to

Effect on Ageing and Cerium Addition on Magnesium Alloy

2024-01-5209

12/10/2024

Magnesium (Mg) alloys are becoming ever more ubiquitous as the need for lighter and stronger alloys has increased significantly in the past decades. Mg alloy grade AZ91D is embedded in 0.5 of cerium have a high strength-to-weight ratio and lower specific density, which is useful in the case of automobile applications. An inconclusive study by Lagowski has shown that interrupted age hardening of AZ magnesium alloy increases the yield strength by around 10%. An investigation on the developed AZ91D+0.5Ce alloy subjected to various ageing treatments was carried out in this present study. The various aged samples were investigated by optical microscopy and scanning electron microscopy analysis. The yield strength was also evaluated quantitatively as a function of ageing parameters. A significant increase in yield strength and hardness values was observed in the artificially aged samples due to the precipitation of Mg17Al12 phases.

Mechanical Properties of Heat Treated Wrought Steels

J413_202412 (Current)

12/05/2024

The figures in this SAE Information Report illustrate the principle that, regardless of composition, steels of the same cross-sectional hardness produced by tempering after through hardening will have approximately the same longitudinal1 tensile strength at room temperature. Figure 1 shows the relation between hardness and longitudinal tensile strength of 0.30 to 0.50% carbon steels in the fully hardened and tempered, as rolled, normalized, and annealed conditions. Figure 2 showing the relation between longitudinal tensile strength and yield strength, and Figure 3 illustrating longitudinal tensile strength versus reduction of area, are typical of steels in the quenched and tempered condition. Figure 3 shows the direct relationship between ductility and hardness and illustrates the fact that the reduction of area decreases as hardness increases, and that, for a given hardness, the reduction of area is generally higher for alloy steels than for plain carbon steels. It is evident from

Comparison of Bake Hardening Effects on AHSSs and Extruded Aluminum Alloys Applied in BEV Reinforcement Structures

2024-01-2240

04/09/2024

At the dawn of battery electric vehicles (BEVs), protection of automotive battery systems as well as passengers, especially from severe side impact, has become one of the latest and most challenging topics in the BEV crashworthiness designs. Accordingly, two material-selection concepts are being justified by the automotive industry: either heavy-gauge extruded aluminum alloys or light-gauge advanced high-strength steels (AHSSs) shall be the optimal materials to fabricate the reinforcement structures to satisfy both the safety and lightweight requirements. In the meantime, such a justification also motivated an ongoing C-STARTM (Cliffs Steel Tube as Reinforcement) Protection project, in which a series of modularized steel tube assemblies, were demonstrated to be more cost-efficient, sustainable, design-flexible, and manufacturable than the equivalent extruded aluminum alloy beams as BEV reinforcement structures.

A Comparative Analysis on Corrosion Behavior on Precipitation Hardened Stainless Steel Weldments for Car Parts

2023-28-0149

11/10/2023

Precipitation Hardened Stainless Steel (PHSS) is one of the martensitic steels that possess exceptional strength and corrosion resistance. Because of its characteristics, this PHSS is exclusively adopted in numerous engineering uses such as nuclear, chemical and marine industries. Welding is one of the important methods of joining that helps to make weldments with better performance characteristics. Corrosion behaviour is one of the important characteristics that contribute hugely to marine and other corrosion-related environments and also this is the most common problem for most of the manufacturing industries. The goal of this study was to analyze the PHSS weldments’ corrosive behavior and compare it with that of the two commonly used welding processes, namely MIG and TIG. The corrosive properties of the weldments were evaluated using various mediums, such as nitric acid, ferric chloride, and Oxalic acid. The weight loss procedure was utilized to calculate the PHSS weldments

Effect of Varying Levels of Work Hardening and Bake Hardening on the Mechanical Properties of Dual Phase Steels

2023-28-1331

In most cases, the properties of a metal are evaluated in their as rolled condition, prior to any work hardening or bake hardening. But in the Automotive World, these steels get work hardened during the forming process and bake hardened in the paint shop. The goal of this paper is to evaluate the variations in the performance of Dual Phase (DP) steels and understand the most optimized method of testing and property generation. This method can then be used to extrapolate to real automotive components. Dual Phase Steels or DP Steels contain a mixture of Ferrite & Martensite from which they derive their name. They are a part of the advanced high strength and ultra-high strength steels steel family according to World Auto Steels. The Ferrite phase, with its iron content contributes to the material displaying an increased level of ductility whilst, the martensitic phase provides the steel with increased mechanical strength. These two properties together enable the steel to be highly

Development and Performance Studies of a Lightweight AA6061/Ti Particulate Surface Composite through Friction Stir Processing

2023-28-1303

05/25/2023

Surface engineering is becoming increasingly crucial for several automotive and aerospace components that involve intense surface interactions. Friction stir processing (FSP) has emerged as an effective surface modification and hardening technique in recent days. The technique also allows the incorporation of reinforcement into the modified surface to enhance the strength and hardness further. This work applied FSP to develop a pure Ti particulate reinforced AA6061 metal matrix composite (MMC). Six different strategies were adapted (in the form of micro grooves, micro drills on the surface) to effectively infuse reinforcement on the alloy surface. Microstructural changes before and after FSP were studied using SEM and EBSD. Other tests such as post-mortem EDS, XRD, hardness, and compression were also done to examine the performance of developed composite. Microstructural lineaments revealed a more uniform dispersion of reinforcement particles in the matrix when the particles were

Methods of Measuring Case Depth

J423_202305 (Current)

05/22/2023

Case hardening may be defined as a process for hardening a ferrous material in such a manner that the surface layer, known as the case, is substantially harder than the remaining material, known as the core. The process embraces carburizing, nitriding, carbonitriding, cyaniding, induction, and flame hardening. In every instance, chemical composition, mechanical properties, or both are affected by such practice. This testing procedure describes various methods for measuring the depth to which change has been made in either chemical composition or mechanical properties. Each procedure has its own area of application established through proved practice, and no single method is advocated for all purposes. Methods employed for determining the depth of case are either chemical, mechanical, or visual, and the specimens or parts may be subjected to the described test either in the soft or hardened condition. The measured case depth may then be reported as either effective or total case depth

Prediction of Surface Finish on Hardened Bearing Steel Machined by Ceramic Cutting Tool

05-16-03-0021

05/17/2023

Prediction of the surface finish of hardened bearing steels was estimated in machining with ceramic uncoated cutting tools under various process parameters using two statistical approaches. A second-order (quadratic) regression model (MQR, multiple quantile regression) for the surface finish was developed and then compared with the artificial neural network (ANN) method based on the coefficient determination (R 2), root mean square error (RMSE), and percentage error (PE). The experimental results exhibited that cutting speed was the dominant parameter, but feed rate and depth of cut were insignificant in terms of the Pareto chart and analysis of variance (ANOVA). The optimum surface finish in machining bearing steel was achieved at 100 m/min speed, 0.1 mm/revolution (rev) feed rate, and 0.6 mm depth of cut. In addition, the ANN model revealed a better performance than that of MQR for predicting the surface finish when machining the hardened bearing steels because R 2 was about 0.787

Design of a Test Geometry to Characterize Sheared Edge Fracture in a Uniaxial Bending Mode

2023-01-0730

04/11/2023

The characterization of sheet metals under in-plane uniaxial bending is challenging due to the aspect ratios involved that can cause buckling. Anti-buckling plates can be employed but require compensation for contact pressure and friction effects. Recently, a novel in-plane bending fixture was developed to allow for unconstrained sample rotation that does not require an anti-buckling device. The objective of the present study is to design the sample geometry for sheared edge fracture characterization under in-plane bending along with a methodology to resolve the strains exactly at the edge. A series of virtual experiments were conducted for a 1.0 mm thick model material with different hardening rates to identify the influence of gage section length, height, and the radius of the transition region on the bend ratio and potential for buckling. Two specimen geometries are proposed with one suited for constitutive characterization and the other for sheared edge fracture. It is shown that
