中文摘要: |
采用真空电弧炉熔炼和真空管退火,制得Dy-Al-Ti三元合金试样,通过X射线衍射(XRD)分析,并辅以差热分析(DTA)、扫描电子显微镜(SEM)分析、能谱仪(EDS)分析等测试技术,对实验样品进行表征,研究了Dy-Al-Ti三元合金系600℃等温截面中的物相关系,确定了Dy-Al-Ti三元系600℃等温截面的两相、三相区边界以及固溶度,并构建了Dy-Al-Ti三元系600℃等温截面相图。研究结果表明,Dy-Al-Ti三元系600 ℃等温截面由14个单相区、27个两相区和14个三相区组成,并证实了两个三元化合物相Ti4Al43Dy6 和Ti2Al20Dy在600℃的存在。 |
英文摘要: |
The Dy-Al-Ti ternary alloys were melted in a vacuum arc furnace and then were annealed in a vacuum tube. By means of X-ray powder diffraction with the aid of differential thermal analysis and metallographic microstructure analysis, the test sample was characterized and the phase relationship in the Dy-Al-Ti ternary system at 600 ℃ was investigated. Then the boundary of two-phase regions and three-phase regions of islthermal section of Dy-Al-Ti ternary system and its solid solution degree were determined at 600 ℃. The isothermal section phase diagram of Dy-Al-Ti ternary system was structured. The results show that this ternary system at 600 ℃ contains 14 single-phase regions, 27 two-phase regions and 14 three-phase regions. Two ternary compounds Ti4Al43Dy and Ti2Al20Dy are confirmed in this system at 600 ℃. |
