摘　　要：研究了密度不同的８２ＷＮｉＣｕ（Ⅰ）、８２ＷＮｉＣｕ（Ⅱ）以及８２ＷＮｉＣｕＡｇ合金，在１０２０，１０７０，１１２０，１１７０℃下进行ＨＩＰ技术处理后合金性能的变化规律。８２ＷＮｉＣｕ（Ⅰ）、８２ＷＮｉＣｕ（Ⅱ）（１１２０℃下）以及８２ＷＮｉＣｕＡｇ合金（１０２０℃下）经过ＨＩＰ技术处理，拉伸强度分别提高７０％，８２％和６０％，密度分别提高０５％，２７％和０６４％。Two kinds of alloys of different densities, 82WNiCu(1) and 82WNiCu(2) and a kind of 82WNiCuAg alloy were treated by hot isostatic pressing (HIP) at 1 020 ℃, 1 070 ℃, 1120 ℃ and 1 170 ℃ respectively to examine the change regularity of their physicomechanical properties. The results showed that after the first two alloys were treated by HIP at 1 120 ℃ and the latter alloy by HIP at 1 020 ℃, their tensile strengths were increased by 70%,82% and 60%, and their densities by 05%, 27% and 064%, respectively.
