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.

Journal ArticleDOI
Effects of stress relief coupled with reduced EBW energy on flow formed maraging steel weldment
TL;DR: In this paper, a flow formed C-250 maraging steel tubing was welded by electron beam welded (EBW) process and subsequently age hardened, and the tensile strength was increased by 12% and the percentage elongation was remarkably increased by 92%.
Journal ArticleDOI
Microstructural analyses of aluminum-magnesium-silicon alloys welded by pulsed Nd: YAG laser welding
TL;DR: In this paper, the effect of preheating on the microstructure and hot crack creation in the pulsed laser welding of AA 6061 was investigated by an optical microscope and field emission electron microscopy.
Journal ArticleDOI
Solidification cracking susceptibility of ferritic stainless steels using Modified Varestraint Transvarestraint (MVT) method
TL;DR: In this article, the authors used the Modified Varestraint Transvarestrain (MVT) test to investigate the solidification cracking susceptibility of an unstabilised, a Nb-stabilised and two (Ti,+ nb) dual-Stabilised ferritic stainless steels.
Journal ArticleDOI
In-situ fabrication of TiC-Al2O3 and TiB2-TiC-Al2O3 composite coatings on 304 stainless steel surface using GTAW process
TL;DR: In this paper, in-situ composite coatings of TiC-Al2O3, as well as TiB2-TiC-B4C were applied on the surface of 304 stainless steel by using combining, welding and self-combustion synthesis with different current welding.
