Speech Title: Influence of Corrosion on Mechanical Properties of PSMC Al Alloy A356 for Automotive Applications
Abstract: Aluminum alloy A356 was prepared by permanent steel mold casting (PSMC). To determine the influence of corrosion on the mechanical behavior and energy-absorption capability of the alloy, the as-cast PSMC A356 alloy was immersed in 3.5 and 10.0% corrosive solutions and mechanically tested. The results of tensile tests showed that the ultimate tensile strength (UTS), yield strength (YS), elongation (ef), modulus, tensile toughness and resilience of the as-cast alloy decreased from 182.84 MPa, 111.86 MPa, 2.5%, 65.03 GPa, 3.68 MJ/m3, and 96.20 kJ/m3 to 135.40 MPa, 68.27 MPa, 2.3%, 34.13 GPa, 2.34 MJ/m3, and 68.28 kJ/m3 for 3.5% solution, and 115.07 MPa, 60.36 MPa, 1.9%, 26.83 GPa, 1.67 MJ/m3, and 67.91 kJ/m3 for 10.0% solution. The corrosion caused significant degradation in strength, ductility, and resilience of the alloy, with more pronounced deterioration at higher corrosion concentration. The microstructure analyses with help of scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) revealed that the presence of corrosion pits and the formation of corrosion products on the surface of the corroded alloy could promote the crack initiation and growth. These findings indicated that corrosion severely compromised the load-bearing capacity and elastic energy absorption of the alloy, highlighting the importance of corrosion control for maintaining long-term mechanical reliability in service environments.
