TL;DR: A review of the emerging research on additive manufacturing of metallic materials is provided in this article, which provides a comprehensive overview of the physical processes and the underlying science of metallurgical structure and properties of the deposited parts.

TL;DR: In this article, three-dimensional viscoplastic flow and heat transfer during friction stir welding of mild steel was investigated both experimentally and theoretically, and the equations of conservation of mass, momentum and energy were solved in three dimensions using spatially variable thermo-physical properties and a methodology adapted from well established previous work in fusion welding.

TL;DR: In this article, a well-tested, three-dimensional, transient heat transfer and fluid flow model is used to accurately calculate transient temperature field for the residual stress and distortion modeling.

TL;DR: In this paper, the Gibbs and Langmuir adsorption isotherms were used to calculate the entropy and enthalpy of surface active components such as oxygen, sulfur, selenium, and tellurium.

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.
