Abstract
Stress-strain measurements were carried out on a Pb-2Â wt%Cd alloy at different strain rates from 6.4Ã10â4Â to 1.0Ã10â2Â sâ1 and in the temperature range from 433 to 503Â K. The material's dynamic stress-strain response, strain rate, temperature effects and possible deformation mechanisms are discussed. The hot working parameters such as yield stress; ultimate stress, elastic modulus and the total strain were estimated as function of temperature and strain rate to evaluate the structural changes during transformation. Nevertheless, the effect of the transformation on the activation energy and the strain rate sensitivity parameter was studied. Furthermore, the microstructure of the studied samples was investigated below and above the transition temperature (0.65 Tm) using optical microscopy and X-ray analysis.
