结果表明，在等径角轧制过程中，板材在模具转角处受到剪应力和压应力的作用；随通道间隙的增加，板材的变形由剪切变形演变为剪切+弯曲变形，甚至弯曲变形；由于剪应力的作用，AZ31镁合金板材的晶粒取向由普通轧制所形成的基面取向转变为等径角轧制后的非基面取向，随着剪切变形量的减小，基面沿轧制方向的偏转角度也逐渐减小。

On the other hand, steam can be used to restrain the side reaction such as hydrogen transfer reaction so as to increase the yield of light olefins by diluting the concentration of the reactant. In addition, minor steam can react with the feed hydrocarbon resulting in the decrease of coke and the formation of active hydrogen without the increase of hydrogen gas and light saturates that is not desirable.

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.
