对以W-Ni-Fe为代表的高比重合金,从选择合适合金成份,多元合金化,烧结气氛,烧结后处理,高温抗氧化性和抗腐蚀性,断口形貌等方面讨论了其工艺技术的合理配置问题。并从这些方面详细讨论了影响高比重合金性能的具体因素。另外还介绍了近年来高比重合金的发展状况。
The W-Ni-Fe represented by the high proportion of the alloy, from the choice of the appropriate alloy composition, multi-alloying, sintering atmosphere, post-sintering treatment, high temperature oxidation resistance and corrosion resistance, fracture morphology and other aspects of its technology The reasonable allocation problem. And from these aspects discussed in detail the impact of high specific gravity alloy specific factors. Also introduced in recent years, the development of high proportion of alloy.
