Abstract: | The phase relationships of the Cu–Ti–Sn ternary system at 473 K have been investigated mainly by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM), optical microscopy (OM) and differential thermal analysis (DTA). The isothermal section consists of 17 single-phase regions, 33 two-phase regions and 17 three-phase regions. The existence of 12 binary compounds and 2 ternary compounds, namely Cu4Ti, Cu3Ti2, Cu4Ti3, CuTi, CuTi2, Cu3Sn, Cu6Sn5, Ti3Sn, Ti2Sn, Ti5Sn3, Ti6Sn5, Ti2Sn3, CuTi5Sn3 and CuTiSn, are confirmed in the Cu–Ti–Sn ternary system at 473 K. No new ternary compound is found. The maximum solid solubility of Cu in Ti6Sn5 was approximately 10 at.% Cu. |
