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。

The height of the Ke peak is independent of the grainsize while that of this peak is proportional to the number of the bamboo boundary containing in the specimen.
例如,葛峰的高度不随晶粒尺寸而变,而竹节峰的高度则与试样中所含的竹节晶界的数目成正比。

Then the morphology was observed by optical microscope and SEM. The grainsize of austenite, the number of martensite in austenite grains and the spacing of the lath martensite were measured.
