摘要

通过对43种退火三元合金的物相鉴定和分析，建立了400℃时的等温截面Zr-Cu-Bi相图。采用扫描电镜（SEM）、x射线能谱（EDS）、x射线衍射（XRD）和差示扫描量热法（DSC）进行研究。在上述研究的基础上，确定了τ1 - Zr5CuBi3、τ2 - Zr5CuBi2、τ3 - ZrCuBi、τ4 - Zr2CuBi、τ5 - Zr2Cu3Bi、τ6 - ZrCu2Bi六个相的存在区，并确定了它们之间的相平衡。测定了以二元化合物为基础的固溶体的存在程度。利用本文报道的实验晶体学数据，采用紧密结合线性松饼锡轨道（TB-LMTO-ASA）方法计算了化合物的电子结构。

Synthesis and characterization of new alloys of ternary Zr-Cu-Bi system

An isothermal cross-section of the Zr-Cu-Bi phase diagram at 400 °C was constructed by phase identification and analysis of 43 annealed ternary alloys. Scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and differential scanning calorimetry (DSC) studies were performed. Based on the above-mentioned studies, the area of existence of six phases was established: τ₁ - Zr₅CuBi₃, τ₂ - Zr₅CuBi₂, τ₃ - ZrCuBi, τ₄ - Zr₂CuBi, τ₅ - Zr₂Cu₃Bi, τ₆ - ZrCu₂Bi, and the phase equilibria between them were determined. The extent of solid solutions based on binary compounds was determined. The electronic structures of the compounds were calculated using the tight-binding linear muffin-tin orbital (TB-LMTO-ASA) method using experimental crystallographic data reported here.
