It has been indicated that the strengthening mechanism of the weld metal is the dislocation, a number of second island phases and fine grainsize.
指出增加变形速率使近缝区金属强化机制为位错强化、一定数量的岛状第二相强化和细晶粒强化。

In most cases, the deformed rocks within ductile shear zones are mylonites, because rock grainsize obviously reduced and strengthening foliation (lineation) developed.
