Comparison of the Heat Treatment Response of Wrought and SSM-HPDC Alloy 6082
The natural and artificial aging responses of wrought and SSM-HPDC alloy 6082 are compared. It is shown that the heat treatment response of this Al-Mg-Si alloy is not influenced by differences in microstructures produced by different processing routes. Wrought alloy 6082 is known to experience an unfavourable effect of prior natural aging on the subsequent artificial aging response, which was also found for SSM-HPDC 6082 in this study. The tensile properties of SSM-HPDC 6082-T6 agree well with those specified for wrought 6082-T6, except for a much lower ductility of the SSM-HPDC variant.
