Abstract
Measurements of the Hf diffusion in alpha-Ti were made by heavy ions R utherford backscattering spectrometry (HIRBS). The range of temperatur e covered was 900-1145 K. The Arrhenius plot is a straight line for th e total range of temperature covered with Q = 254+/-30 kJ/mol and D-0 = (4+/-2)x10(-6) m(2)/s. These values are in excellent agreement with previous ones obtained with the RBS technique in the range 823-1023 K. The results suggest that there is no Fe influence on Hf diffusion in alpha-Ti.
