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0~3GPa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=5.135km/s,横波声速为ct=2.987km/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=157.4GPa,E=393.0GPa,K=260.2GPa,λ=155.3GPa,μ=157.4GPa,ν=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。
Using the two-sided top press and the six-sided top press as the pressure device, the high-pressure ultrasonic measurements of 93 tungsten alloy materials were carried out respectively. The transverse and longitudinal wave velocities of 93 tungsten alloy under normal conditions and the change of the longitudinal wave velocity with the pressure in the pressure range of 0 ~ 3GPa were measured. The measurement results are as follows: At room temperature and pressure, 93 Tungsten alloy longitudinal wave velocity cL = 5.135km / s, transverse wave velocity ct = 2.987km / s. The relationship between the velocity of longitudinal wave and pressure changes as follows: cL = 5.053 + 0.602p (GPa). The calculated mechanical parameters of 93 Tungsten alloy are: G = 157.4GPa, E = 393.0GPa, K = 260.2GPa, λ = 155.3GPa, μ = 157.4GPa, ν = 0.248. After comparing the results of the two ultrasonic measurements and the shock wave measurement data, these parameters are reliable.
