中文摘要:
      本实验通过采用电子探针显微分析和X-ray衍射分析方法实验研究了Co-Cu-Zn三元体系在800°C和1000°C时的相平衡。在这两个等温截面中均未发现三元化合物。在800°C等温截面,Co在β-CuZn相中的固溶度为32.36%,Cu在β1-CoZn相中的固溶度为5.28%。除此之外,γ-Co5Zn21和γ-Cu5Zn8具有相同的晶体结构,因此,它们之间形成了一个贯穿连续固溶体相。1000°C的等温截面中,β-CuZn相、β1-CoZn相、γ-Co5Zn21相、γ-Cu5Zn8相都消失了。随着温度从800°C上升到1000°C,液相区域增大。

英文摘要:
      The phase equilibria of the Cu-Co-Zn ternary system at 800°C and 1000°C were investigated by means of electron probe microanalysis and X-ray diffraction. No ternary compound was found. At 800°C, the solubility of Co in the β-CuZn, and Cu in the β1-CoZn at 800°C were 32.36 at.% and 5.28 at.%, respectively. The γ-Co5Zn21 and γ-Cu5Zn8 showed the same crystal structure, an infinite region of mutual solubility was observed in the Cu-Co-Zn ternary system. It was confirmed that as the temperature rises from 800°C to 1000°C, the liquid-phase region was further expanded. The isothermal section of 1000oC was simple. The phase of β-CuZn, β1-CoZn, γ-Co5Zn21 and γ-Cu5Zn8 was disappeared. The region of liquid phase is very large.
