Heat transfer and fluid flow during keyhole mode laser welding of tantalum, Ti–6Al–4V, 304L stainless steel and vanadium
TL;DR: In this paper, a keyhole model is developed and tested on tantalum, Ti-6Al-4V, 304L stainless steel and vanadium, and a turbulence model based on Prandtl's mixing length hypothesis is used to estimate the effective viscosity and thermal conductivity in the liquid region.
Journal ArticleDOI
Evolution of solidification texture during additive manufacturing
TL;DR: Numerical modeling can not only provide a deeper understanding of the solidification growth patterns during the additive manufacturing, it also serves as a basis for customizing solidification textures which are important for properties and performance of components.
Journal ArticleDOI
Numerical simulation of three-dimensional heat transfer and plastic flow during friction stir welding
TL;DR: In this paper, a three-dimensional visco-plastic flow of metals and the temperature fields in friction stir welding have been modeled based on the previous work on thermomechanical processing of metals.
Journal ArticleDOI
Printability of alloys for additive manufacturing
TL;DR: The printability, or the ability of an alloy to avoid these defects, can be examined by developing and testing appropriate theories, and a theoretical scaling analysis is used to test vulnerability of various alloys to thermal distortion.
Journal ArticleDOI
Scientific, technological and economic issues in metal printing and their solutions
