Phase Diagram Calculation and Experimental Research on Au-Pd-Zr Alloys

利用相图计算软件Pandat计算了Au-Pd-Zr合金的液相面投影图、室温(25℃)的等温截面图、xAu-xPd-Zr合金系的垂直截面图,同时选取了36Au-36Pd-28Zr (at％)合金,基于相图计算与实验验证相结合的方法,研究了该合金的相平衡以及凝固过程.利用光学显微镜、扫描电镜、能谱仪对该合金的室温平衡相组成进行了验证.结果表明,相平衡热力学计算结果与实验结果比较吻合,36Au-36Pd-28Zr合金的凝固顺序为:L→L+PdaZr→L+Pd3Zr+ZrAu2→Pd3Zr+ZrAu2+ZrAu3.
