Journal ArticleDOI
A process model for friction stir welding of age hardening aluminum alloys
TL;DR: In this article, a numerical 3D heat flow model for friction stir welding (FSW) is developed, based on the method of finite differences, which is implemented in MATLAB 5.2 and validated by comparison with in-situ thermocouple measurements and experimental hardness profiles.
Journal ArticleDOI
Modelling of the age hardening behaviour of Al–Mg–Si alloys
TL;DR: In this paper, a special control volume formulation of the classical precipitation model for coupled nucleation, growth and coarsening has been adopted to describe the evolution of the particle size distribution with time during thermal processing of Al-Mg-Si alloys.
Journal ArticleDOI
Modelling of non-isothermal transformations in alloys containing a particle distribution
Ole Runar Myhr,Øystein Grong +1 more
TL;DR: In this paper, a framework for modeling coupled nucleation, growth and coarsening in diluted alloys is presented, based on the method of finite differences, where the particle distribution is divided into a series of discrete size classes, each represented by a control volume.
Journal ArticleDOI
Modelling of the microstructure and strength evolution in Al–Mg–Si alloys during multistage thermal processing
TL;DR: In this article, a numerical solution is presented, capable of handling nucleation, growth and coarsening, and likewise dissolution, of hardening precipitates in Al-Mg-Si alloys during ageing, welding and post weld heat treatment (PWHT).
