Abstract: Hot forming die quenching (HFDQ) is an emerging process in which sheet metal is successively stamped at high temperature and quenched by the cold tool. The microstructure and mechanical properties of ultra high strength steel parts formed by the HFDQ process are a function of the cooling rate achieved during the quenching step. Optimal energy absorption for crash performance can be obtained by a local reduction of the cooling rate in order to form softer, more ductile phases such as bainite. Accurate character… Show more
