Developing Ultra‐High Strength Bainitic Steel by Hot Stamping Process and Anisothermal Holding
steel research international, Volume 95, Issue 9, September 2024.This study aims to produce bainitic steel parts after hot stamping/press hardening by using an anisothermal annealing. A bainitic matrix including martensite, fine‐grained ferrite, and retained austenite was obtained and analyzed by characterization techniquies. Different cooling strategies were employed to alter the microstructure to achieve a tensile
