Abstract

The solubility and diffusion of Au in α-Ti have been studied in a 823–1023 K temperature range using the Rutherford backscattering technique. For this purpose we have implanted Au into α-Ti samples. Our results show that the solubility of Au varies between 0.2 and 0.35 at.%. In addition, we found that the diffusion coefficients follow a normal Arrhenius behavior with Q=260 kJ/mol and D o=1.9×10−5 m2/s1. These values are typical for a substitutional diffusion mechanism.
