An integrated hardening model for the heat treatment of extruded 6082

An integrated hardening model for the heat treatment of extruded 6082
Hardening in extruded aluminium alloy 6082 has been modelled as a function of solution treatment temperature, quench rate, ageing temperature and ageing time. Solution treatment and ageing temperature effects are treated using a regular solution model with reference to the Al-Mg2Si quasi-binary phase diagram. Quench factor analysis is applied to approximate time-temperature-transformation (TTT) curves, enabling the prediction of hardness values for both step quenching and continuous cooling treatments. Age hardening is modelled using concepts from existing approaches (such as the Shercliff and Ashby age hardening model [H. R. Shercliff and M. F. Ashby, Acta Metall. Mater., 1990, 38, 1789]), as well as novel elements taking account of the effects of solution treatment temperature and quench rate on ageing kinetics. The scope, accuracy and limitations of the model are discussed.

Abstract

Hardening in extruded aluminium alloy 6082 has been modelled as a function of solution treatment temperature, quench rate, ageing temperature and ageing time. Solution treatment and ageing temperature effects are treated using a regular solution model with reference to the Al-Mg2Si quasi-binary phase diagram. Quench factor analysis is applied to approximate time-temperature-transformation (TTT) curves, enabling the prediction of hardness values for both step quenching and continuous cooling treatments. Age hardening is modelled using concepts from existing approaches (such as the Shercliff and Ashby age hardening model [H. R. Shercliff and M. F. Ashby, Acta Metall. Mater., 1990, 38, 1789]), as well as novel elements taking account of the effects of solution treatment temperature and quench rate on ageing kinetics. The scope, accuracy and limitations of the model are discussed.
