W-Mo composites with different mass fractions of W and Mo were prepared at1473 K by Spark Plasma Sintering technique. The transverse and longitudinal wave velocities of thesamples were accurately measured using the ultrasonic pulse echo overlap method, and the waveimpedance values of the samples were then calculated. The results show that W-Mo system compositesare of nearly full dense and can be regarded as a mechanical mixture system. The ideal mixture modelwas adopted to estimate the wave impedance of W-Mo composites. Comparisons with the experimentaldata demonstrate that the suggested model is sufficiently accurate to predict the wave impedance ofW-Mo composites. 展开更多
