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.

The Effect of Plasma Arc Process Parameters on the Properties of Dissimilar AISI 1040/AISI 304 Steel Plate Welds
TL;DR: In this paper, 10 mm thick AISI 1040 and 304 steel plates were welded in the butt position without pretreatment by plasma transferred arc (PTA) welding technique.
Microchemical analysis of non-metallic inclusions in C-MN steel shielded metal arc welds by analytical transmission electron microscopy
TL;DR: In this article, the inclusions were predicted by the use of equilibrium thermodynamics and their effect on the microstructure and mechanical properties of the steel weld metals investigated, and the results indicated that, for weld metals containing small amounts of M (13 ppm), the inclusion were comprised of MnO-SiO2, TiO (maybe as a compound) and Cu(Mn)S.
Dissimilar laser welding of NiTi shape memory alloy to austenitic stainless steel archwires
TL;DR: Saeed et al. as mentioned in this paper investigated the dissimilar welding of NiTi shape memory alloy to AISI 304 austenitic stainless steel archwires and found that the obtained microstructure from the laser weld of these alloys has a dendritic and nonhomogeneous structure.
