研究了W含量为15%~30%的Ni-W合金的组织形貌、相结构以及显微硬度。结果表明:不同W含量的4种合金都形成了Ni(W)单相固溶体;随着W含量的增加,晶界处氧化物增加,合金显微硬度也随着增加。
The morphology, phase structure and microhardness of Ni-W alloy with W content of 15% -30% were studied. The results show that Ni (W) single phase solid solution is formed on all the four alloys with different W contents. With the increase of W content, the grain boundary oxides increase and the microhardness increases.
