Evaluation of Shear Trim Edge in HSLA Steel for Automotive Application2026-26-0286To be published on 01/16/2026
Quality of the Shear Trimmed edge of HSLA 550 steels is significantly affected by process variations such as Shear Trimming Clearance, trim tolerance, burr height and clamping force. All these parameters largely influence the characteristics of the Shear Affected Zone, a region on sheet metal where it undergoes deformation during the trimming process. The Shear Affected Zone is predominantly vulnerable to failure due to work hardening and the effects of strain rate, induced by the tonnage during the trimming operation. To assess the edge ductility of these materials, Tensile, Fatigue Strength, Die Punch Clearance, Roughness and Hardness Tests are carried out. These tests are crucial for applications that demand high formability and resistance to edge failure. Virtual simulation of edge trimming operation using elastoplastic material models in LS-Dyna have been performed to gain insights into burr formation and damage evolution during shearing. These simulations act as a precursor to

Evaluating the Suitability of ADC12 for Sand Casting: Filling, Solidification, and Mechanical Properties2026-26-0296To be published on 01/16/2026
This research investigates the applicability of ADC12 aluminum alloy in sand casting processes and compares its casting behavior and performance with that of conventionally sand-cast alloys such as A356 and AlSi10Mg. ADC12 is primarily utilized in high-pressure die casting (HPDC) and low-pressure die casting (LPDC) due to its excellent castability, pressure tightness, and favorable mechanical properties in thin-walled components. However, its use in sand casting is minimal globally, primarily due to the alloy’s high silicon and iron content, which can lead to poor feeding characteristics, increased porosity, and structural non-uniformity in non-pressurized molds. In this study, 3 mm thick test castings were produced using conventional sand casting methods, with particular attention to mold and core design to simulate challenging flow and solidification conditions. Comparative castings of A356 and AlSi10Mg were also produced under identical conditions to establish performance baselines

A numerical approach to optimize the flow characteristics for the enhancement of casting soundness of Al 6061 alloy die-casting2026-26-0284To be published on 01/16/2026
The optimization of flow characteristics such as filling time, flow velocity, viscosity and temperature play a vital role in the die-casting to enhance the casting soundness. Experimental trial and error methods for optimizing the flow characteristics of mold filling are costlier and time-consuming methods. A digital approach could significantly minimize the cost and time for the prediction of the flow characteristics of the casting. Z-Cast Pro is the casting simulation software used for simulating the whole casting process such as filling, solidification etc. This software basically utilizes the finite difference and finite volume approximation techniques to numerically unravel the molten metal flow and solidification equations. In this study, A 3D model of the valve housing is used to analyze the mold-filling behavior through high and low-speed plunger movement of the molten Al 6061 alloy using Z-Cast Pro software version 24. Higher-speed plunger movement required a total mold

Predictive Analysis and Risk Management of Nickel-Plated Aluminum Automotive Parts Exposed to Harsh Environmental Conditions2026-26-0305To be published on 01/16/2026
Aluminium is widely used across various industries due to its lightweight properties, high strength-to-weight ratio, and cost-effectiveness. However, its susceptibility to corrosion, particularly in harsh environmental conditions, presents challenges to its long-term durability and performance. To mitigate these issues, nickel plating was applied as a protective measure, creating a barrier to minimize aluminums' direct exposure to corrosive environments and enhance its resistance to degradation. In this study, nickel-plated aluminum was subjected to controlled corrosion testing under simulated real-world conditions, including high humidity, saline atmospheres, and industrial pollutants. The primary objective was to evaluate the effectiveness and longevity of nickel plating as a corrosion prevention method. Periodic observations and measurements were conducted to monitor material changes, such as surface degradation and corrosion product formation. The findings highlight the critical

Hydrogen Embrittlement in Galvanized High Carbon Steel Components of Automotive Seat Slider Assembly2026-26-0302To be published on 01/16/2026
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

Advancing Welding Excellence through Numerical Simulation Based Approach: A Multi Pass Welding Case Study on Cast Iron Coupons2026-26-0457To be published on 01/16/2026
The Automotive industry extensively uses cast iron for its exceptional 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

Hypoid Gear Performance Redefined: Addressing Scoring and Whine Noise Concerns2026-26-0078To be published on 01/16/2026
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, gear scoring and whine noise frequently emerge as critical challenges, leading to reduced durability and compromised performance of the vehicle. This study focuses on the design and process improvements aimed at addressing these concerns while enhancing the overall performance and reliability of hypoid gears. Design enhancements include macro geometry refinements, material upgrades, and modifications in the heat treatment process. These changes improved key mechanical properties such as contact stress, bending strength, impact strength, and motion transmission error (MTE). Process optimizations involved precise control over carburizing, hardening, and quenching temperatures, as well as adjustments in quenching pressure. These measures

A Study on the Microstructural Changes and Corrosion Behavior and Mechanical Properties in Stainless Steel Welds with Single Versus Double Stabilized Welding Wires2026-26-0288To be published on 01/16/2026
This research investigates the influence of stainless-steel stabilization, using single (titanium) and double (titanium and niobium) stabilized ferritic weld wires, on the metallurgical, mechanical, and corrosion behaviors of weld seams and their heat-affected zones (HAZ). Two ferritic stainless-steel samples, one stabilized with titanium (Sample No. 1) and the other with titanium and niobium (Sample No. 2), were selected for this comparative study. The research involved comprehensive analysis, including fatigue testing of the welded joints produced by both types of wires (430LNb & 430LNbTi), correlated with detailed microstructural and mechanical characterization. Metallographic analysis via optical microscopy revealed distinct features of the HAZ and weld seam, focusing on grain size, shape, and weld geometry. Micro-hardness measurements were conducted to elucidate the mechanical properties of the weld seams. Tensile testing was performed using a Universal Testing Machine to assess

Non-metallic inclusions in carburizing steels as a contributory factor for the formation of carbide net2026-26-0290To be published on 01/16/2026
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

Balancing global and local formability properties through Nb microalloying2026-26-0303To be published on 01/16/2026
David Martin, CBMM Asia Bernardo Barile, CBMM Europe BV Caio Pisano, CBMM Europe BV Automotive high strength steels have specific microstructure-dependent forming characteristics. Global formability is generally associated with high uniform strain values which imply good drawability and stretch forming properties driven by pronounced work hardening. Local formability on the other hand is often measured by various fracture strain values—generally higher in single phase steels. In this respect, the so-called ‘local/global formability map’ concept has been established not only to provide a comprehensive methodology to characterize existing automotive steels but also to enable improvement strategies toward more balanced forming characteristics. Niobium (Nb) microalloying is a powerful tool to achieve both property improvement in general and property balance in particular. More than two decades of research has demonstrated that Nb-induced microstructural optimization is applicable to HSLA

Effect of the Flow Forming Process on the Mechanical properties and Microstructure of GDC & LPDC cast aluminum alloy wheels.2026-26-0298To be published on 01/16/2026
Aluminum alloy wheels have become the preferred choice over steel wheels due to their lightweight nature, enhanced aesthetics, and contribution to improved fuel efficiency. Traditionally, these wheels are manufactured using methods such as Gravity Die Casting (GDC) [1] or Low Pressure Die Casting (LPDC) [2]. As vehicle dynamics engineers continue to increase tire sizes to optimize handling performance, the corresponding increase in wheel rim size and weight poses a challenge for maintaining low unsprung mass, which is critical for ride quality. To address this, weight reduction has become a priority. Flow forming [3,4], an advanced wheel production technique, offers a solution for reducing rim weight. This process employs high-pressure rollers to shape a metal disc into a wheel, specifically deforming the rim section while leaving the spoke and hub regions unaffected. By decreasing rim thickness, flow forming not only reduces overall wheel weight but also enhances strength and

Multi-Material Front Structures: A Pathway to Safer and More Sustainable Vehicle Design2026-26-0456To be published on 01/16/2026
Frontal crash structures play a vital role in occupant safety, but traditional designs often involve a trade-off between structural strength and weight efficiency. In the pursuit of safer and more sustainable mobility, this study explores a physics-based methodology that leverages the principle of dynamic equilibrium to guide the integration of dissimilar materials in front-end vehicle structures. Specifically, we examine a novel configuration wherein aluminum High pressure die cast (HPDC) is introduced in swan neck region of the front longitudinal member, while retaining steel in the frontal crush zone. This arrangement aims to redistribute crash loads and control deformation mechanisms, enabling improved energy absorption without compromising structural integrity. To evaluate the proposed strategy, a series of detailed finite element simulations were conducted using LS-DYNA, a widely adopted tool for vehicle crash analysis. The results reveal that the dynamic equilibrium approach
