一、绪言 1930年以来对W-Ni-Fe烧结合金进行了广泛的研究,力求改善其机械性能,扩大其在高强度部件上的应用范围。初期,Kfock对W-Ni-Fe烧结合金机械性能进行了探讨,而后,Ekbom又进一步进行了研究。Ekbom对合金的断裂行为同以试验速度和温度为变量之间的函数关系进行了探讨。此外,German还对钨合金的成份进行了探索。 另一方面,Meyer等人还针对91％钨合金的屈服强度与断裂强度受其在试验时的拉 I. INTRODUCTION W-Ni-Fe sintered alloys have been extensively studied since 1930 in an effort to improve their mechanical properties and expand their use in high-strength components. Initially, Kfock discussed the mechanical properties of W-Ni-Fe sintered alloys, and then Ekbom further studied. Ekbom alloy fracture behavior with the test speed and temperature as a function of the relationship between variables were discussed. In addition, German has also explored the composition of tungsten alloys. Meyer et al., On the other hand, also target 91% tungsten alloy yield strength and fracture strength
