| 英文摘要 | Phase equilibria in the ternary Cu-Zr-Si system at 750 and 900 degrees C have been experimentally investigated via electron probe micro-analyzer (EPMA) and X-ray diffraction (XRD) analysis on the equilibrated alloys. The results show the presence of eight three-phase regions at 750 degrees C and seven three-phase regions at 900 degrees C. Four ternary phase: tau(1) (Zr3Cu4Si6, tI26-Zr3Cu4Si6), tau(4) (Zr3Cu4Si4, oI(22)-Gd3Cu4Ge4), tau(s) (ZrCuSi, oP12-Co2Si), and tau(6) (Zr3Cu4 Si-2, 2hP9-Fe2P) were confirmed to exist in the Cu-Zr-Si ternary system at 750 and 900 degrees C. At 900 degrees C, the dark gray phase, the chemical composition of which is close to eta-Cu3Si, is confirmed to be the liquid phase. Moreover, the solubilities of Cu in ZrSi2, SiZr and Zr3Si2 are considerably small. The solubility of Zr in eta-Cu3Si is determined to be negligible. The newly determined phase equilibria of the Cu-Zr-Si system in this work can provide important experimental data for the thermodynamic assessment of the Cu-Zr-Si system and to develop the Cu-Zr-Si alloys and related transition metal silicides. |
