摘    要：借助三元扩散偶/电子探针分析技术测 定了W－Ni－Co三元系在1100℃时的等混截面.它包含了：3个单相区,即bcc(W),μ－Co₇W₆和FCC;3个两相区,即 bcc(W)+μ－Co₇W₆,bcc(W)+fcc和fcc十μ－Co₇W₆;1个三相区,即bcc(W)+fcc+μ－Co₇W₆.

Abstract: An experimental study of the isothermal section of the W-Ni-Co system at 1100℃ has been made using the diffusion triple technique and electron microprobe analysis. Three single-phase regions (bcc(W), fee and μ-CoW₆), three two-phase regions (bcc (W) +fcc, bcc (W) +μ-Co7W6 and fcc + μ-Co₇W₆) and one three-phase region (bcc (W) + fcc + μ-Co₇W₆ )are included in the section.
