摘要
利用扫描电镜和Hopkinson型试验装置 ,对 97钨的显微组织、断裂方式、及准静态和动态力学性能进行了研究。结果表明 ,97钨是具有较大压拉比的敏感材料 。
The 97% tungsten alloy fabricated by P/M technique is examined experimentally in this paper, the dynamic compression test is realized by Hopkinson bar and the damage mechanisms are examined by tension test from a Scanning Electronic Microscope. It is found that the damage mechanism of this alloy in tension is mainly the crack initiation and propagation inside of the tungsten particles, the material is brittle in tension, it however has a very good ductility in compression.
