Creep cracks seem always to initiate at inherent casting pores and slowly propa-gate anisotropically along the (001) planes, perpendecular to axis of stress applied, upto the final fast fracture. Creep cracks can also nucleate at fractured carbides or at in-terfaces between carbides and matrix in the alloys containing more carbon.

Fine carbides precipitated from ferrite in 16-6 Cr-Mo, 16-2.5-6 Cr-Ni-Mo, and 16-5-6 Cr-Ni-Mo steels in the early stages of ageing are metastable, during prolonged heating they redissolve and are gradually replaced by χ-phase. Some residual carbides serve as the nuclei of the growing χ-phase. The structure of quenched 16-15-6 Cr-Ni-Mo steel is austenitic, during subsequent heating only M_6C and M_(23)C_6 mixed carbides are precipitated.

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.
