The microsturcture characteristics of M2 cast-strip were studied with such experimental methods as metallographic analysis, SEM, XRD and TEM[0]. The effect of sub-rapid solidification on the size, type and distribution of eutectic carbides in M2 cast-strip was analyzed. The effect of heat treatment temperature and its holding time on the eutectic carbides in M2 cast-strip was explored. The eveolution of metastable phase of M2C eutectic carbide during the heat treatment period and the decomposition dynamics concerned were researched. The M2 cast-strips were rolled into thin strips and the effect of deformation ratio on carbides in M2 cast-strip was examined. Then these thin strips were comparied with those that were produced by conventional technology on carbide, hardness, red-hardness and bend strength. At last the rolled M2 cast-strips were made into saw blades and their cutting performance was experimented on in tools factories and then compared with that of similar products produced by conventional technology.
