Abstract

Phase relations in Ti-Cu-Pt ternary system have been studied through diffusion- triple technique combined with alloy sampling. Assisted with Electron Probe Microanalysis (EPMA) and x-ray diffraction (XRD) techniques, isothermal sections at 1073 and 973 K of this ternary system were constructed, which consist of 16 three-phased regions at 1073 and 973 K, where two ternary phases, respectively formulated as Ti(Cu,Pt)2 and Ti(Cu,Pt)3, were detected to exist stably at 1073 and 973 K. By the way, the 2 binary compounds, Ti3Pt5 and TiPt3− were found to be stable at 1073 and 973 K.
