摘要
用脉冲回波法测量了ＴＣ４、１６Ｍｎ、Ａｌ＿２Ｏ＿３陶瓷从室温到１０００℃的纵波与横波声速，由声速得到绝热弹性模量。给出了Ｅ、Ｇ随温度变化的回归方程。对材料熔点做了估算。
The velocities of logitudinal and shear waves in TC4,1 6Mn and Al_2O_3 ceramicswere measured by a pulse-echo technique from 15～1000℃.Adiabatic elastic moduli are calcu-lated from these velocities.Regression equations of E,G vs temperature are given by the regressionanalysis. The melting temperatures are estimated in the paper.
