摘　　要：通过实验分析了 90W和 93W钨合金在动加载时其断裂机理及特性以及侵彻时其微观结构响应的异同点。通过对比发现 ,二者的断裂机理基本相似 ,但侵彻时 ,由于 90W钨合金中存在较多的粘结相而使得其蘑菇头较小 ,其中的钨颗粒变形也较小 ;只在The difference of micro behavior between 90W and 93W tungsten alloy under impact dynamics was analysed. Their fracture feature is alike. But when penetrating, because of more matrixes in 90W, the end of penetrator of 90W is smaller and its shape changing of W grains is also smaller. So, only in 93W, the adiabatic shearing bands can be found.
