WebApr 8, 2024 · The comprehension of austenite formation during post-weld heat treatment in weld metal deposits is a key aspect to predict the final properties. In the present work, the transformation kinetics of martensite into austenite in SMSS all-weld metal deposit was studied by dilatometry, considering the effect of the heating rate (1, 10 and 100 °C/s). WebSep 1, 2024 · Dual-Phase (DP) steels belong to the first generation of advanced high strength steels (AHSS) [1] and are widely used in the automotive industry. DP steels consist of hard martensite particles dispersed in a soft ferritic matrix, leading to a good combination of strength and ductility [1], [2], [3].In DP steels, martensite is typically formed from the …
