A review on selective laser sintering/melting (SLS/SLM) of aluminium alloy powders: Processing, microstructure, and properties
TL;DR: In this article, the state of the art in selective laser sintering/melting (SLS/SLM) processing of aluminium powders is reviewed from different perspectives, including powder metallurgy (P/M), pulsed electric current (PECS), and laser welding of aluminium alloys.
Journal ArticleDOI
Dislocation network in additive manufactured steel breaks strength–ductility trade-off
Leifeng Liu,Qingqing Ding,Yuan Zhong,Ji Zou,Jing Wu,Yu-Lung Chiu,Jixue Li,Ze Zhang,Qian Yu,Zhijian Shen +9 more
TL;DR: In this article, the authors show that the pre-existing dislocation network, which maintains its configuration during the entire plastic deformation, is an ideal modulator that is able to slow down but not entirely block the dislocation motion.
Journal ArticleDOI
Critical review of automotive steels spot welding: process, structure and properties
TL;DR: In this article, the fundamental understanding of structure-properties relationship in automotive steels resistance spot welds is discussed. And a brief review of friction stir spot welding, as an alternative to RSW, is also included.
Journal ArticleDOI
Revisiting fundamental welding concepts to improve additive manufacturing: From theory to practice
TL;DR: In this article, a unified equation to compute the energy density is proposed to compare works performed with distinct equipment and experimental conditions, covering the major process parameters: power, travel speed, heat source dimension, hatch distance, deposited layer thickness and material grain size.
Journal ArticleDOI
Using deep neural network with small dataset to predict material defects
TL;DR: This study attempted to predict solidification defects by DNN regression with a small dataset that contains 487 data points and found that a pre-trained and fine-tuned DNN shows better generalization performance over shallow neural network, support vector machine, and DNN trained by conventional methods.

Effect of magnetic stirring on grain structure refinement: Part 1 – Autogenous nickel alloy welds
Yong Chae Lim,Xinghua Yu,Jungho Cho,J.M. Sosa,Dave F. Farson,S. Suresh Babu,Steven L. McCracken,B. Flesner +7 more
TL;DR: In this paper, the effects of circular magnetic arc deflection (arc stirring) on grain structure refinement of gas tungsten arc weld beads made in Inconel 690 substrates were investigated.
Journal ArticleDOI
Microstructure and Mechanical Properties of Narrow Gap Laser-Arc Hybrid Welded 40 mm Thick Mild Steel
TL;DR: In this research, 40 mm thick mild steel was welded by narrow gap laser-arc hybrid welding, providing an alternative technique for improving the efficiency and quality of welding thick sections.
Journal ArticleDOI
Effect of Cobalt on Microstructure and Wear Resistance of Ni-Based Alloy Coating Fabricated by Laser Cladding
TL;DR: In this article, the effects of Co content on the microstructure, composition, hardness, and wear properties of the claddings were studied by scanning electron microscopy (SEM), an electron probe microanalyzer (EPMA), X-ray diffraction (XRD), a hardness tester, and a wear tester.
Journal ArticleDOI
Modelling of hot cracking in welding with a cellular automaton combined with an intergranular fluid flow model
Cyril Bordreuil,Aurélie Niel +1 more
TL;DR: In this paper, a numerical model that integrates thermal and mechanical properties of welds is developed to investigate solidification cracking, and the model is able to describe some hot cracking phenomena observed during experimental tests, but it is difficult to discriminate the influence of different phenomena because they are all connected.
Journal ArticleDOI
Effect of filler alloy composition on post-weld heat treatment cracking in GTA welded cast Inconel 738LC superalloy
TL;DR: In this article, the effect of filler alloy composition on post-weld heat treatment (PWHT) cracking in Inconel 738LC (IN-738LC) superalloy was investigated.
