摘要
采用真空电弧熔炼法熔炼W-Cu-Zr三元系合金,在900℃下退火90天后取出样品立即淬火,采用XRD、SEM等测定其平衡显微组织。实验测得W-Cu-Zr三元系900℃等温截面中有4个三相区:Cu51Zr14+(Cu)+(W)、(W)+Cu51Zr14+Cu8Zr3、CuZr_2+W_2Zr+Cu_8Zr_3、(Zr)+CuZr_2+W_2Zr,1个两相区:(W)+W_2Zr。W-Cu-Zr三元体系中没有检测到三元化合物。二元化合物Cu_(51)Zr_(14)、Cu_8Zr_3、CuZr_2中最大的含W量分别为2.88、1.15、1.7 at.%;W2Zr中最大的含Cu量为7.71 at.%。
W-Cu-Zr ternary system alloys were prepared by vacuum arc-melting method, the alloys annealed at 900 ℃for 90 days were quenched immediately, equilibrium microstrueture were determined by XRD and SEM, et al. Four three-phase regions, Cu51Zr14＋（Cu）＋（W）, （W）＋Cu51Zr14＋Cu8Zr3, CuZr2＋W2Zr＋Cu8Zr3, （Zr）＋CuZr2＋W2Zr and one two-phase region （W）＋W2Zr have been determined experimentally in the isothermal section of the W-Cu-Zr ternary system at 900 ℃. No ternary compound was detected in W-Cu-Zr ternary system.The maximum solubility of W in Cu51Zr14, Cu8Zr3, CuZr2 were 2.88, 1.15, 1.7 at.%, respectively, the maximum solubility of Cu in W2Zr was 7.71 at.%.
