When narrower chill zone formed, the long columnar dendrites grow into the melt and then the fine equiaxed cellular structure reveals in upper melt region nearby surface. The substructure of cellular grains and dendrites was observed to consist of martensite and retained austenite, while the carbides as M_6C, Cr_7C_3 and MC distributed at their interfaces. It is believed that the high microhardness, HV_(0.1)=865—960, of the laser fused structure of the alloy is due to the occurrence of martensite.
