在局部范围,原子偏离其正常的点阵平衡位置,造成点阵畸变。 在金属材料中, 点阵畸变会使得晶体能量升高,阻碍位错的运动,产生材料的强化,韧性降低。
发现点阵参数随摩尔分数浓度呈线性变化,点阵畸变主要受组分的尺寸效应影响;
The lattice parameters a vary linearly with the molar fractions, the lattice distortion is mainly affected by the size effect of components.
相变温度的变化是由于电子辐照产生的点缺陷造成了马氏体相点阵畸变和有序度的变化,从而产生马氏体稳定化。
The point defects induced by electron irradiation make the lattice distortion of martensite phase and the increase of the ordering degree which bring about the stabilization of martensite.
利用这套图解曲线或表达式,使得在各种可能线型组合下的嵌镶尺寸和点阵畸变的测算可用手工处理,并使电子计算机快速计算成为可能。
By using the above diagrammatic curves and corresponding formulae, we have made the calculation possible directly by hand, or quickly on-line by computer.
