Phase equilibria in the Ni-Si-Zr ternary system have been investigated experimentally by means of x-ray diffraction and electron probe micro-analyzer on equilibrated ternary alloys. Four ternary phases were detected at 1023 and 1173 K. The Ni16Si7Zr6 phase tends to present in two different contrasts and has a wide homogeneity range. The reported Ni2Si9Zr14 phase is not detected in this work. It is proposed that the Ni2Si9Zr14 phase is unstable at these temperatures. As for the binary phases, Ni5Zr and Ni7Zr2 dissolve appreciable amounts of Si and γNi31Si12, βNi3Si, δNi2Si, NiSi2 exhibit a considerable solubility of Zr.

Ni-Si-Zr 三元系统等温截面的实验研究在 1023 和 1173 K

Ni-Si-Zr 三元体系中的相平衡已经通过 X 射线衍射和电子探针显微分析仪在平衡的三元合金上进行了实验研究。在 1023 和 1173 K 处检测到四个三元相。 Ni16Si7Zr6 相倾向于以两种不同的对比度存在并且具有很宽的均质范围。在这项工作中没有检测到报告的 Ni2Si9Zr14 相。建议 Ni2Si9Zr14 相在这些温度下是不稳定的。对于二元相，Ni5Zr 和 Ni7Zr2 溶解了大量的 Si，而​​ γNi31Si12、βNi3Si、δNi2Si、NiSi2 显示出相当大的 Zr 溶解度。
