Deformation combined with quenching and carbon partitioning,i.e.,causing steel to deform in austenitizing temperature range,phase transformation to occur during quenching in the steel,and carbon to partition from martensite into untransformed austenite,may control amount of hard martensite and amount of soft retained austenite in the steel,being a novel hot forming-quenching-carbon partitioning technology.The use of such heat treatment practice makes it possible that a composite microstructure consisting of nano-scale dislocation martensite and retained austenite is developed,being capable of increasing mechanical properties but not damaging strength for steel.%变形与相变和碳分配相结合，即钢在奥氏体区变形以细化晶粒、获得高强度，在淬火过程中钢发生相变和碳分配，可实现对硬相马氏体和软相残留奥氏体的调控，是一种新型热成形淬火碳分配工艺。这一工艺方法可使钢获得纳米级位错型马氏体和残留奥氏体的复合组织，在不损害钢的强度的前提下，提高其力学性能。
