“…[6,7] This approach entails the wide utilization of high-strength steel, aluminum alloy, magnesium alloy, and carbon fiber-reinforced polymer (CFRP) in vehicle design. [8][9][10][11][12][13] Due to the physical and mechanical differences of these materials as well as the formation of brittle intermetallic compounds, conventional resistance spot welding methods for steel joints fail to achieve an effective joint for dissimilar materials. [14][15][16] Consequently, several new joining technologies have emerged to address this challenge, including self-piercing riveting (SPR), [17] flow drill screw (FDS), [18] friction stir welding, [19] friction stir spot welding, [20] and cold metal transition welding.…”

This study delves into the corrosion behavior of riveted joints with electrophoretic treatment in a neutral salt spray environment using tensile test and surface analysis. The results showed that the open‐circuit potentials of the dual‐phase steels (590DP and 780DP) exceeded those of the AlSi10MnMg‐T7 and JDA1b die‐casting aluminum alloys by 100 mV, and exceeded that of the AA6063‐T6 extruded aluminum alloy by 50 mV. AlSi10MnMg‐T7 and JDA1b die‐casting aluminum alloys were more susceptible to corrosion in contrast to the AA6063‐T6 extruded aluminum alloy. The corrosion mechanism of the steel/aluminum riveted joints was not only galvanic corrosion but also oxygen concentration polarization. Over the 720‐h corrosion period, the failure loads of the riveted joints were not reduced at all. On the contrary, they increased at least 17% for the two‐sheet self‐piercing riveting (SPR) joints, 6% for the three‐sheet SPR joints, and 4% for the flow drill screw joints.

The cyclic behavior of materials under load and its influence on the mechanical properties of materials have always been the focus of engineering research. In this study, high strength steel was successfully welded by laser welding. The microstructure of each region of the high strength steel DP590 post-welding was meticulously analyzed. Additionally, 500 cycles of low-cycle fatigue tests of laser welded high strength steel were carried out by using asymmetric stress control method. After fatigue test, tensile test shall be carried out on some samples. Under the specific combination of mean stress and stress amplitude, compare the specimens that have not been fatigue tested with those that have been fatigue tested, the change of properties of laser welded high strength steel joint under asymmetric cyclic load was analyzed. The results showed that, due to cyclic hardening, the tensile strength of the sample increased to 601 MPa and the yield strength to 325 MPa. Compared with the original sample, the tensile strength and yield strength of the sample after asymmetric cycling had increased by 8.65% and 31.3%, respectively.

“…Ultra-light Steel Auto Body (ULSAB) has 19% lighter weight, high strength, and low manufacturing cost compared with the traditional steel body. Besides, although the cost of traditional steel is low, traditional steel provides greater thickness compared to HSS (yield strength between 210 and 550 MPa) and Ultra-High Strength Steel (UTSS) (yield strength over 550 MPa) [8].…”

Global energy demand is currently contributing to a severe problem of rising fuel prices for automobile users. One solution is to reduce the weight of the car body to improve fuel efficiency and reduce fuel costs. The choice of car body material can achieve this purpose. This paper will present the criteria such as stiffness, strength, and density to determine the suitability of substituting traditional materials, such as mild steel and carbon steel, with new materials High Strength Steel (HSS), aluminum alloys, and Long Fiber Thermoplastic (LFT). A literature review of the research is done to showcase the challenges traditional materials experience and how the development of these three new materials can overcome these challenges. Results from the case study show the feasibility of implementing these new materials in an automobile. More future research should be conducted to overcome the challenges and limitations posed by using these new materials, focusing on the low-cost replacement, manufacturing, and co-joining techniques of car body parts.
