Abstract

The stage-I work-hardening behavior of Cd single crystals from stress-strain curve measurements has been investigated as a function of temperature and strain-rate. The results show that the temperature and the strain-rate introduce opposite effects on the work-hardening behavior. The stress was found to be approximately linear on the square root of strain for both low and high strain values at different temperatures. There is an inflexion point at intermediate strains. This inflexion point moves to higher strain values with increasing temperature.
