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
Evaluation of processing parameters on PTA hardfacing surfaces
TL;DR: In this article, the effect of the sharpening angle on a tungsten electrode, plasma gas flow, and torch nozzle constriction on the characteristics of a weld bead deposited by the hardfacing by plasma transferred arc (PTA) was investigated.
Journal ArticleDOI
Improving weldability of aged 25Cr–35Ni heat resistant steel/alloy 800 dissimilar welds
TL;DR: In this paper, the effects of a preweld solution annealing, heat input, interpass temperature and type of filler metal were investigated and it was found that the most important step to improve weldability and to reduce cracking susceptibility was solution-annealing.
Journal ArticleDOI
Hydrocarbon-metal reactions during metal arc welding under oil (MAW-UO)
H Almostaneer,Christopher A. Cadigan,Stephen Liu,David L. Olson,Ryan M. Richards,Hongjun Liang +5 more
TL;DR: In this article, the authors used an automated metal arc welding set-up with a continuous wire feed for in situ internal repairs of in service cross-country pipelines, tanks and vessels.
Journal ArticleDOI
Analytical Description of the Influence of the Welding Parameters on the Hot Cracking Susceptibility of Laser Beam Welds in Aluminum Alloys
TL;DR: In this paper, the impact of the welding parameters on the strain rate limit that a laser welded seam can withstand without the formation of hot cracks was analyzed for the case of laser beam welding of the technical aluminum alloy AA6016.
Journal ArticleDOI
Projection friction stir spot welding: a pathway to produce strong keyhole-free welds
TL;DR: In this paper, projection friction stir spot welding is used to produce keyhole-free friction stir welds based on a pinless tool method involving using a specially designed pin-less tool.
