Numerical simulation of thermal behavior and multicomponent mass transfer in direct laser deposition of Co-base alloy on steel
TL;DR: In this paper, an improved 3D numerical model is proposed to simulate the heat transfer, fluid flow, solidification and multicomponent mass transport in direct laser deposition of Co-base alloy on steel.
Journal ArticleDOI
Modeling of thermal behavior and mass transport in multi-layer laser additive manufacturing of Ni-based alloy on cast iron
TL;DR: In this article, a predictive three-dimensional numerical model is developed to understand the multi-physical processes such as thermal behavior, Marangoni effect, composition transport, solidification behavior, and dendrite growth in multi-layer additive manufacturing of Ni-based alloy on cast iron.
Journal ArticleDOI
Surface-active element transport and its effect on liquid metal flow in laser-assisted additive manufacturing
TL;DR: In this article, an improved surface tension model is proposed to take into account the influence of sulfur content and temperature at the surface of a melt pool, and the results show that the sulfur redistribution leads to transitional Marangoni flow.
Journal ArticleDOI
Heat and mass transfer in laser dissimilar welding of stainless steel and nickel
TL;DR: In this paper, a three-dimensional heat and mass transfer model is used to simulate the welding process, based on the solution of the equations of mass, momentum, energy conservation and solute transport in weld pool.
