%X Laser hardening can increase the hardness of Cr12 steel up to about1100HV and fine its microstructure.It is mainly due to the improvement of dissolution ofcarbides and homogenity of elements diffusion,by which the composition of austenite,po-sition of Ms and content of retained austenite can all be changed.The highest hardness iscorresponding to the least content of retained austenite after laser treatment.
