Coupled transient heat transfer—microstructure weld computations (part B)
TLDR
In this article, the Watt/Coon algorithm is coupled with a transient finite element heat transfer analysis for computing the microstructure as a function of space and time ( x, y, z, t ) in the heat-affected zone (HAZ) of low alloy steel welds.About:

Physical processes in fusion welding
Tarasankar Debroy,Stan A David +1 more
TL;DR: In recent years, major advances have taken place in our understanding of welding processes and welded materials because of the complexity of fusion welding processes, solution of many important contemporary problems in fusion welding requires an interdisciplinary approach as mentioned in this paper.

Residual Stress and Distortion Modeling of Electron Beam Direct Manufacturing Ti-6Al-4V
TL;DR: In this paper, a finite element model is developed for predicting the thermo-mechanical response of Ti-6Al-4V during electron beam deposition, and both in situ distortion and post-process residual stress measurements suggest that stress relaxation occurs during the deposition of a single-bead wide, 16-layer-high wall built for model validation.

Welding Residual Stresses in Ferritic Power Plant Steels
TL;DR: In this article, the authors review metallurgical issues that arise in ferritic steel welds, relate these to the difficulties in calculating residual stresses, and propose a method to estimate residual stresses in the case of ferritic alloys.

Process modelling applied to 6082-T6 aluminium weldments—I. Reaction kinetics
O.R. Myhr,Øystein Grong +1 more
TL;DR: In this article, an overall process model for the microstructural stability of 6082-T6 aluminium alloys at elevated temperatures is presented, composed of elements derived from thermodynamics, kinetic theory and simple dislocation mechanics, and allows predictions of the hardness distribution after reheating and subsequent natural ageing of the base metal for a wide range of operational conditions.
