研究了热等静压WC-Co合金的各种力学性能，并与常规烧结的合金进行了比较。结果表明：（1）热等静压合金的横向断裂强度和室温疲劳强度明显高于常规烧结合金。(2)随着温度的升高，热等静压处理对横向断裂强度的影响逐渐减小。由于这种趋势，WC-10%Co合金在900°C以上高温下的横向断裂强度不受热等静压处理的影响。(3)断裂韧性（KIC）不受HIP处理的影响。
Various mechanical properties of hot isostatic pressed WC-Co alloy were investigated and compared with those of conventionally sintered alloy. The results obtained are as follows: (1) Transverse rupture strength and fatigue strength at room temperature of hot isostatic pressed alloys become remarkably larger than those of conventionally sintered alloy. (2) The effect of HIP treatment on transverse rupture strength decreases gradually with the rise of temperature. As a reult of this tendency, trnasverse rupture strength of WC-10%Co alloy at high temperatures above 900°C becomes to be unaffected with HIP treatment. (3) Fracture toughness (KIC) is unaffected with HIP treatment.
