回火的功能主要是析出相如碳化物的充分析出,而晶粒早在淬火时候已经形成,回火无法改变的

As one of efforts for the simultaneous improvement of strength and ductility in ultrafine-grained (UFG) alloys, the grain refining process using the strain-induced martensite and its reverse transformations (called SIMRT process) in metastable austenitic alloys has been attractive recently. The SIMRT process can easily make UFG alloys by a single cycle of conventional cold rolling and annealing without severe plastic deformation, which have an excellent combination of both uniform elongation.
and strength.
