Abstract
The effect of structural integrity on the tensile deformation of A206-T71 castings was evaluated. To generate a wide range of structural integrity, some castings were subjected to hot isostatic pressing (HIP) at various conditions and the others received no remedial processing. The analysis of true stress-strain curves of all castings showed that A206-T71 follows the Kocks-Mecking Stage III work hardening model in both non-HIPed and HIPed conditions. Nevertheless distinct differences were found within and between the HIPed and non-HIPed conditions. Kocks-Mecking parameters were correlated to elongation and toughness (strain energy). Structural integrity or quality, as measured by relative toughness, was found to have two types of effects on the Kocks-Mecking parameters. These effects are discussed in the paper.
