摘      要：Advanced high-strength steels have been widely used to improve the crashworthiness and lightweight of *** from the popular cold stamping,hot forming of boron-alloyed manganese steels,such as 22MnB5,could produce ultra-high-strength steel parts without springback and with accurate control of ***,hot-formed medium-Mn steels could have many advantages,including better mechanical properties and lower production cost,over hot-formed *** paper reviews the hot forming process in the automotive industry,hot-formed steel grades,and medium-Mn steel grades and their application in hot forming in *** particular,the adaptabilities of medium-Mn steels and the presently popular 22MnB5 into hot forming were compared *** research should focus on the technological issues encountered in hot forming of medium-Mn steels to promote their commercialization.
