【摘要】 研究了钨基合金中钨的含量与其显微组织、断裂方式及力学性能之间的关系。结果表明，随着钨含量的增加，钨邻接值增加．合金的抗拉强度增加；当钨含量到达一定值后，强度可达最高，再增加钨含量，强度则急剧下降。更多还原

【Abstract】 The relationship of tungstencontent microstructure breaking way and mechanical properties in W-Ni-Fealloy was studied. The results show that with tungsten content increasing in alloy,tensilelity strength increasing- Whentungsten content reached some value,the tensilelity strength reached maximum- But the tungsten content increased a-gain,the tensilelity strength decreased quickly.[更多还原
