摘要： The isothermal section of the Nb-W-Zr system at 1373K has been successfully measured by means of electron probe microanalysis(EPMA) on diffusion couples. This isothermal section includes two single-phase regions, "α" and (W,Nb)2Zr, and one two-phase region "α" + (W,Nb)2Zr. The maximum solid solubility of Nb in (W,Nb)2Zr is 12.23at.% Nb.
