中文摘要:
      利用X射线衍射、扫描电子显微镜及能谱分析等手段建立了Mn-Zr-Si三元合金体系600℃等温截面。研究发现,Mn-Zr-Si三元合金系在600℃下存在一个成分为Mn4Si7Zr4的新物相,其结构与Fe4Si7Zr4结构相同,点阵常数为a = 1.3027 nm,c = 0.515 nm。研究还发现高温相Zr5Si3在600℃是稳定的,未观察到Zr3Si的存在。此外,本文的工作同时还确认了三元化合物MnSi2Zr和MnSiZr在600℃下是稳定存在,未发现前人提到三元化合物Mn4Si6Zr3。

英文摘要:
      The isothermal section of the Mn-Zr-Si ternary system at 600℃ was investigated by using X-ray diffraction, scanning electron microscope and energy dispersive analysis. A new termary compound was discovered. This compound was found to be isostrutural to Fe4Si7Zr4 with tetralgonal structure and cell parameters of a = 1.3027 nm, c = 0.515 nm. A quite different conclusion was obstained for the Zr-Si binary system comparing to results in the literatures. No the evidence was found to support the existence of Zr3Si at 600℃, which was taken as a stable phase in the Zr-Si system. Moreover, XRD and SEM/EDS revealed that Zr5Si3 was a stable phase at 600℃. In addition, MnSi2Zr and MnSiZr were confirmed at 600℃ while Mn4Si6Zr3 is not found in the present work.
