在80°~500°K范围内，用脉冲回波法测定了镁银和铜的三个独立的弹性常数，所有弹性常数的温度系数都是正常的，但都小于其组成元素的平均值。镁银的各向异性因子很高，而镁铜的各向异性因子很低，正如人们从它们各自的晶体构型中所预期的那样。研究发现，镁铜合金的弹性行为与金刚石结构相似。
The three independent elastic constants of MgAg and MgCu2have been determined by the pulse-echo method from 80° to 500°K. The temperature coefficients of all the elastic constants are normal but smaller than the average of their constituent elements. The anisotropy factor is high for MgAg and low for MgCu2, as one would expect from their respective crystallographic configurations. The elastic behavior of MgCu2was found to be similar to that of the diamond structure.
