| 摘 要： | 实验得到 CuZnAl 合金在热弹性马氏体相变时体积膨胀,但从点阵常数的变化来看应为体积收缩.应用马氏体相变晶体学表象理论(WLR 理论)并考虑到马氏体变态间的自协调效应,导出相变时体积变化率与点阵常数的数学关系.计算值与实验值能很好地吻合.

| Abstract: | Experimental results confirm that volume expansion occurs during th-ermoelastic martensitic transformation in CuZnAl alloy,which is contrary with the results from the change in lattice parameter.The phenomenological crystallogra-phic theory is employed to deal with this problem.On the basis of self-accommoda-tion among the martensite variants,a mathematic expression of the relationship between the volume change rate and the lattice parameter can be deduced.There is a good agreement between calculated and experimental results. |
