Thermally activated process in deformed alpha titanium

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Deformation behaviour of alpha titanium has been studied in the temperature range 295 to 914 K. The temperature dependence of the yield stress exhibits an athermal region at temperatures 500–750 K. A non-monotonous temperature dependence of the stress sensitivity parametern, estimated in stress relaxation tests, is observed in the same temperature interval. Possible mechanisms of thermally activated deformation and dynamic strain ageing are considered.
