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.

Use Of Segregation As A Weld Design Opportunity
TL;DR: In this paper, the selection of the optimal Rare Earth (RE) element addition to achieve intragranular precipitation of inoculants for acicular ferrite formation in high strength low alloy steel weld metal is introduced to demonstrate the application of fundamentals of microstructure evolution.
Journal ArticleDOI
Effect of Chloride and Sulfate Ions on the SCC of API-X70 Pipeline Welds in Diluted Carbonated Solutions
TL;DR: In this paper, the authors evaluated the SCC susceptibility of longitudinal weldments of API-5L X-70 PSL1 pipeline steel in diluted bicarbonate solutions with and without the addition of chloride and sulfate ions by using slow strain rate tests (SSRTs).
Dissertation
Experimental sensitivity analysis of welding parameters during transition from globular to spray metal transfer in gas metal arc welding
TL;DR: In this article, the degree of master of technology in Mechanical Engineering at the Peninsula TechnikonCape Town University was submitted towards the degree degree of Master of Technology in Mechanical engineering.
Dissertation
Laser Welding of Medium-Manganese Steel
TL;DR: In this paper, the effects of rapid heating and cooling thermal cycles imposed by laser welding on MMn steel was investigated and the microhardness profiles of large heat input diode laser bead-on-plate (BoP) welds found that the steel was not susceptible to heat affected zone (HAZ) softening.
Proceedings ArticleDOI
Numerical simulation and experimental investigation of laser dissimilar welding of carbon steel and austenitic stainless steel
TL;DR: In this paper, an experimental and numerical investigation on controlling the microstructure and brittle phase formation during laser dissimilar welding of carbon steel to austenitic stainless steel was conducted.
