TL;DR: In this article, the authors developed, tested and utilized a three-dimensional heat transfer and fluid flow model of wire arc additive manufacturing (WAAM) to calculate temperature and velocity fields, deposit shape and size, cooling rates and solidification parameters.

TL;DR: In this article, a simulation of the misorientation angle between the preferred crystalline orientation and the temperature gradient influences both the incubation time and the average wavelength of any initial instability during the planar growth stage, as well as the dendrite growth direction and the primary diameter during the subsequent epitaxial growth stage.

TL;DR: In this paper, a phase field model was developed to investigate the microstructure evolution near the fusion line during solidification of the gas tungsten arc welding (GTAW) pool for aluminum alloy 2A14.

TL;DR: In this article, the microstructural characteristics, element burning loss behavior and their effects on the mechanical properties of the weld beams were studied and it revealed that the weld porosity could be effectively controlled with a lower welding velocity and the crystal enlargement is rather obvious near the weld upper surface.

TL;DR: In this paper, the influence of phase transformations on the transient heat conduction in components made of Ti-6Al-4V during tungsten inert gas (TIG) arc welding is investigated using a coupled thermal and metallurgical model.
