摘　　要：探讨了密度不同的 82 W— Ni— Cu( ) ,82 W— Ni— Cu( )以及 82 W— Ni— Cu—Ag合金 ,于 1 0 2 0 ,1 0 70 ,1 1 2 0 ,1 1 70℃进行 HIP技术处理后合金性能的变化规律。W— Ni—Cu在 1 1 2 0℃ ,W— Ni— Cu— Ag合金在 1 0 2 0℃经 HIP技术处理后 ,拉伸强度分别提高了 2 .61 3 %、 8.1 91 %和3 .2 79% ,密度提高 0 .4 98%、 2 .889%和 0 .676%。Two kinds of 82W-Ni-Cu alloys, Ⅰ and Ⅱ ,differed in density, and one kind of 82W-Ni-Cu-Ag alloy were treated with hot isostatic pressing (HIP) at 1 020 ,1 070,1 120 and 1 170 ℃ respectively to examine the changement regularity of their physicomechanical properties. The results showed that the tensile strength of the 82W-Ni-Cu(Ⅰ),82W-Ni-Cu(Ⅱ) and 82 W-Ni-Cu-Ag alloys HIP treated at 1 120 ℃ is 2 613% ,8 191% and 3 279% higher than that of treated at 1 020 ℃,respectively and also the corresponding density is 0 498%,2 889% and 0 676% higher than that of treated at 1 020 ℃ respectively. And it is feasible obviously to improve the physicomechanical properties of the above alloy materials for making pilot gyrorotor by using HIP treatment technique.
