摘要

摘要: 利用两面顶压机和六面顶压机作为压力装置，分别对93钨合金材料进行了高压超声测量。测得了93钨合金材料在常态下的横、纵波声速及在0~3 GPa压力范围内的纵波声速随压力的变化关系。测量结果为：在常温常压下，93钨合金的纵波声速为cL＝5.135 km/s，横波声速为ct＝2.987 km/s。纵波声速随压力变化的关系式为：cL＝5.053+0.602p（GPa）。估算的93钨合金相关力学参量为：G＝157.4 GPa，E＝393.0 GPa，K＝260.2 GPa，＝155.3 GPa，＝157.4 GPa，＝0.248。经过对两种超声测量方法测量结果的比较及冲击波测量数据的验证，这些参数是可靠的。

Abstract: Longitudinal and transversal sound velocities of 93W alloy were measured by using a belt type and a cubic-type high pressure apparatus, respectively. Results show that under normal temperature and pressure conditions, this tungsten alloy materials have a longitudinal velocity (cL) of 5.135 km/s and transversal velocity (ct) of 2.987 km/s. Pressure dependence of longitudinal velocity is linear in the pressure range up to 3 GPa, with a form of cL=5.053+0.02p, where p is in unit of GPa. Bulk sound velocity calculated from these data is 3.86 km/s, which is quite close to the shock wave experiment results of 4.008 km/s. Other parameters under normal conditions are: shear modulus G=157.4 GPa, Young's modulus E=393.0 GPa, bulk modulus K=260.2 GPa, Lame coefficients =155.3, =157.4, Possion's rate =0.248.
