利用X射线粉末衍射法(XRD),扫描电子显微镜(SEM)和能谱分析(EDX)等方法测定了Zr-Cr-Cu三元系700℃等温截面. 结果表明,此截面由10个单相区、18个两相区和9个三相区组成.第3组元Cr的加入,导致高温CuZr相共析分解温度下降,在700℃时形成稳定的三元相τ.研究确定体系中富锆角...

The isothermal section of Fe-Ni-Zr ternary system at 1198K was experimentally determined using diffusion triple technique together with scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). The results indicate that there are seven binary intermetallic phases, Fe2Zr, FeZr2, NiZ...

The microstructures of both as-cast and homogenized Nd-Fe-B ternary alloys have been studied. The stable phase regions existing in Nd-Fe-B ternary system at room temperature have been established by the microzone composition analysis and the phase identification. Based on the obtained results, an is...
