查询词典 grain

Three are three major actions that Mn effects fracture behavior in the alloy at room temperature, as follow: One is that Mn fines grains, antiphase domains and weakens dislocation clog, which retain formation of cleavage crackle. The second is that Mn decreases APB energy and promotes slop and cross slip, in particular, a large number of cross slip make deformed APBs transform from line type into zigzag type and the APBs interact and cross each other, resulting in propagation of cleavage cracks. The last is that Mn raises the relative proportion of cleavage strength to grain-boundary strength and then restrains formation and propagation of cleavage crack.

Mn对合金室温断裂行为的影响主要反映在三个方面，一是Mn的存在细化晶粒和反相畴，使得位错塞积程度减小，从而阻碍解理裂纹源的生成；二是Mn的存在提高解理强度与晶界强度的相对比值，从而抑制了解理裂纹的形成和扩展；三是Mn降低反相畴界能量、促进超位错的滑移、交滑移，特别是断裂前位错大量的交滑移使形变反相畴由直线型变为折线"Z"字型，反相畴界间的相互作用、相互交错阻碍了解理裂纹的扩展。

In this investigation, the compression behavior of COx argillite with two different grain size distributions, which were obtained by two different crush procedures, was studied by running 1D compression tests with several loading-unloading cycles.

通过开展一维压缩试验，研究2种不同粉碎工艺下获得的粗／细COx土样的压缩特性，结果表明：压缩曲线受粒度成分的影响非常明显，为获得同等压实度，细粒土所需的压实功能较粗粒土高，除此之外，细粒土的压缩指数也高于粗粒土，表现出较强的压缩性；随着土样压实密度的增加，粗／细土样的压缩曲线逐渐靠拢，粒度成分对压实功能影响逐渐减弱；土样卸荷时回弹指数随干密度的增加而增加，受粒度成分的影响不明显；高压实ρ(下标 d=2.0g/立方公分粗粒土样在7 MPa的轴向应力下饱和时，体积发生明显的塌陷现象，饱和后土样的压缩指数小于饱和前，而回弹指数则较饱和前高。
