Lecture
This lecture discusses the failure case of an indoor swimming pool due to stress corrosion cracking in austenitic stainless steel hangers. It covers the negative effects of alloy contents, microstructure inhomogeneities, and the resistance to stress corrosion cracking. The use of advanced high strength steels (AHSS) in automotive engineering is also explored, focusing on TRIP steels and their advantages over other AHSS generations. The presence of retained austenite in TRIP steel and its implications are explained, along with the differences in forming behavior between first and second generation AHSS.
