Abstract
The solubility and diffusion of Au in alpha-Ti have been studied in a 823-1023 K temperature range using the Rutherford backscattering techn ique. For this purpose we have implanted Au into alpha-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 nor mal Arrhenius behavior with Q = 260 kJ/mol and D(o) = 1.9 X 10(-5) m2/ s-1. These values are typical for a substitutional diffusion mechanism .
