therefore, the phase transformation to cbn must be related to the dislocation motion in crystal under high pressure.
而向立方型氮化硼的转变其晶体的切变是必不可少的,这种相变主要依靠高压下位错运动而产生。
supposing there is no interaction between solute atoms, the feature of dislocation motion and the distribution of solutes are obtained at different external stresses in the dynamic simulation.
动态模拟中假设溶质原子之间没有相互作用,得到在不同的外加应力下位错的运动特征和溶质原子的分布状态。
these precipitates inhibit the dislocation motion and result in the strengthening effect.
析出颗粒阻碍位错运动,提高合金的强度。
it was thought that the dislocation motion in grains and grain-boundaries, as an important coordination mechanism, promoted the development of grain-boundary sliding.
