Phase relations in the ternary Ti-Ni-Cusystem at 800 and 870 degrees C

Abstract We have investigated the isothermal cross sections through the ternary phase diagram Tiz.sbnd;Niz.sbnd;Cu at 800 and 870 °C by means of the diffusion couple technique. The results have been corroborated on essential points by the investigation of equilibrated alloys. Use has been made of optical, microprobe a nd X-ray analyses. The results differ from those mentioned in the literature. For two hitherto undescribed ternary intermetallic compounds X-ray diffraction data are given and crystallographic cell parameters are proposed.
