Temperature rise in severe plastic deformation of titanium at small strain-rates

Temperature rise in severe plastic deformation (SPD) of titanium at small strain-rates by machining has been measured using infrared thermography. The temperature rise is shown to be small and unlikely to influence material behavior during the deformation. The temperature distribution in the deformation zones is similar to the strain-rate distribution therein. The deformation mechanisms operative during the SPD are interpreted in terms of the observed temperatures and strain-rates.
