Abstract

A finite element model coupling heat transfer calculations, phase transformations kinetics and internal stresses calculations to simulate laser powder deposition of a titanium alloy is presented. The model was applied to the study of the influence of the deposition parameters on the microstructure, hardness and residual stresses in Ti-6Al-4V thin walls produced by this method.
