Abstract:Based on a selection principle proposed by the authors for adding additive elements to improve the expansion coefficient and other properties of the W-Ni-Cu alloys, the influences of Mn, Ag powders on W-Ni-Cu alloys were investigated and the factors influencing the properties of W-Ni-Cu alloy were also analysed. Besides the possible approaches for developing the novel W-alloys with fairly comprehensive properties have been discussed .
Key words: W-alloy expansion coefficient homogeneity additive elements
