Abstract

Titanium copper compound formations have been studied via Seeman Bohlin x-ray diffractometry and Rutherford backscattering spectrometry. The heat treatment temperature range was 350°C to 475°C and th heat treatment times ranged from 0 to 240 minutes. Tetragonal gamma TiCu formed first at ˜350°C and was sequentially followed by orthorhombic TiCu3 at ˜400°C. From Rutherford backscattering spectrometry analysis it was concluded that the second TiCu3 compound deviated from ideal stoichiometry to a nonstoichiometric Ti0.88Cu3.12 composition
