%X The microstructure features of stainless steel have changed remarkably after laser surface remelting and solidification. Light band, fine cell, cell-dendrite structure and disordered dendrite are found in the surface layer, meanwhile, the causes for their formation have been analyzed. The typical cell-to-dendrite transition is observed at the center of laser melt pool, and a detailed investigation on the transition conditions shows that the critical transition velocity determined by experiment agrees well with the prediction of recent BJT model.Correspondent: PAN Qingyue, Lab.403, Northwestern Polylechnical University, Xi'an 710072
