基于含应变能的微观相场动力学模型,利用结构函数归一化因子和标度函数,对Ni75Cr19Al6合金沉淀后期DO22相的粗化行为进行研究。结果表明:DO22相的结构函数归一化因子和标度函数在沉淀后期阶段均表现出标度行为,加入应变能后,DO22有序畴尺寸在非弹性“软”方向上的长大受到阻碍,DO22有序畴的体积分数也减小,结构函数的归一化结构因子和标度函数曲线峰值均小于未加应变能的值。 Based on the kinetic model of microscopic phase field containing strain energy, the coarsening behavior of DO22 phase in the late stage of precipitation of Ni75Cr19Al6 alloy was studied by using normalization factor and scaling function of structure function. The results show that both the normalization factor and the scaling function of the structure function of DO22 phase show the scaling behavior in the late stage of sedimentation. After adding the strain energy, DO22 grows in the inelastic “soft ” direction Obstructed, the volume fraction of DO22 ordered domains also decreases, and the normalized structure factor and the peak value of the scaling function of the structure function are both smaller than those of the unadjusted strain energy.
