从各向同性连续介质中直线位错之间的弹性交互作用能出发,推导出具有任意Burgers矢量夹角的两平行直刃型位错之间弹性交互作用的滑移力和攀移力表达式指出两平行直刃型位错的弹性交互作用存在三个滑移平衡位置:u1=1;u2=-1,u3=tg,并确定了三个滑移平衡位置成为滑移稳定平衡位置的条件还得到滑移、攀移共同运动情况下两平行直刃型位错在弹性交互作用下的稳态构型分别讨论了紧束缚、弱束缚情况下位错滑移的稳定性
Based on the elastic interaction between linear dislocations in isotropic continuous medium, the expressions of the sliding force and the climbing force of the elastic interaction between two parallel straight-edge dislocations with any Burgers vector angle can be deduced It is pointed out that there exist three slip equilibrium positions for the elastic interaction of two parallel straight edge dislocations: u1 = 1; u2 = -1, u3 = tg, and the conditions that the three slip equilibrium positions become the stable slip equilibrium position The steady-state configurations of two parallel straight-edge dislocations under elastic interaction under the condition of sliding and climbing together are also discussed respectively. The stability of the dislocation slippage under tight and weak constraints are discussed respectively
