    Abstract

    The strain distribution, the temperature evolution during and after testing, and the temperature gradients developed during deformation have been determined in specimens tested in plane strain compression at different strain rates. It is found that the strain distribution patterns are determined by the geometrical configuration of the material during deformation and are not affected by the strain rate. However, the range of variation of local strains within a specimen does increase at high strain rate. This increase is attributed to localized increases of temperature. It is shown that local variations in temperature are measured as a thermocouple crosses an active slip line field. Implications for metallographic studies are drawn.
