摘要：

TEM was used to investigate the microstructure of the laser alloying zone on 65Mn tape-steel surface. The composition of this zone was designed on the basis of M2 high speed steel. The studies indicated that the structure of the laser alloying zone was significantly different from that of a normal M2 steel. Martensite laths dominated and a great amount of highly dispersed granular or short stick-like M(6)C carbides present. Moreover, there was a ball-like noncrystalline phase in some regions.
