Abstract

Commercially pure alpha-titanium was deformed by hot rolling at 268° C for reduction levels of 40%, 60% and 80%. The dislocations densities and types in terms of Burgers Vector Populations at different deformation rates were established using X-ray Peak Profile Analysis. The dislocation model of anisotropic broadening of peak profiles was used to determination the Burgers vector distribution, and their evolution as the deformation proceeds to higher degrees in alpha-titanium samples presented here. It was found that the 〈a〉 dislocation type dominate at all deformation levels investigated in this study. The population of the 〈c+a〉 dislocation type is significant after 40% reduction and it becomes marginal for higher deformation rates. The 〈c〉 type dislocation population was found to be marginal at all deformation levels.
