Khan, I.N., Starink, M.J. and Yan, J.L. (2008) A model for precipitation kinetics and hardening in Al-Cu-Mg alloys Materials Science and Engineering: A, 472, (1-2), pp. 66-74. (doi:10.1016/j.msea.2007.03.033).

Record type: Article


A physically-based numerical model is developed to predict the microstructural evolution and strengthening in Al Cu Mg alloys during isothermal treatments. The modelling of the formation kinetics of the precipitates is based on the Kampmann and Wagner model. The strengthening by the shearable Cu:Mg co clusters is modelled on the basis of modulus strengthening mechanism and the strengthening by the non-shearable S phase precipitates is based on the Orowan looping mechanism. The model predictions are verified by comparing with the strength and differential isothermal calorimetery data on 2024-T351 aluminium alloys. The microstructural development and strength predictions of the model are generally in good agreement with the experimental data.
