摘要: 对93W合金材料进行了超声测量实验,并结合原有的超声测量结果进行了分析比较,提出了可以直接用冲击波速度关系式的三个系数c0 、和来对钨合金的有关力学参量,如G0、K0、G0、K0等进行综合选评的方法。得到了一组对93W合金较为合理的力学参量推荐值。Abstract: This article reports the new ultrasonic data of 93W (a tungsten alloy with 4.3% Ni, 2.45% Fe and 0.35% Co by weight as binder) obtained using different apparatus. We further made some analyses and comparisons with some previous data, including ultrasonic data and Hugoniot parameters, which were measured in our laboratory in the past. As a result, the recommended mechanical parameters approximately suitable for 93W are as follows: G0=132 GPa, Gp=1.79, GT=-0.016 GPa/℃, K0=270 GPa, and Kp=4.11.
