摘要
Optimization of microstructure for new generation advanced high strength steels(AHSS ) for automobiles was briefly reviewed.Two different heat treatments(quenching partitioning austempering/QPA and quenching partitioning tempering/QPT) have been investigated to obtain optimal microstructures,which are made up of martensite(hard phase),retained austenite(soft phase),and carbide or nano-bainite.Combination of hot stamping and newly developed heat treatments is discussed.
