熔炼法制备不同W含量的Ni-W合金的研究

Ni-W Alloys with Different W Content by Melting

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 microstructure, phase composition and microhardness of the Ni-W alloys with W content of 15%-30% were studied. The results show that the phase composition of four kinds of alloys are single phase Ni（W） solid solution in the microstructure; with the increase of the content of W, the oxides of grain boundary increases, and the microhardness also increases.
