Abstract
AbstractA model for non‐isothermal age‐hardening for AlMgSi alloys has been developed. The model is based on the Shercliff–Ashby methodology developed for isothermal heat treatments, and is extended to non‐isothermal heat treatments by combining with the concept of internal state variable approach. During the process of non‐isothermal heat treatment, the sub‐models not only change with time but also change with temperature. However, the constants, which are calibrated by choosing suitable input data for A356, A357 and 6061 taken from open literature, will remain unchanged for any heat treatment conditions for a specific material. Then two‐step ageing is chosen as an example of non‐isothermal heat treatment. The whole ageing curves of yield strength under different two‐step ageing heat treatments are constructed.
