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.

Growth features of crystals in laser-welded aluminium and aluminium alloys
TL;DR: In this article, the formation of weld metal formation at the fusion boundary during laser welding of aluminium and aluminium alloys has been investigated and the growth features of crystals in the weld metal and growth rate of columnar crystals.
Journal ArticleDOI
Influence of Austempering Temperature and Time on the Microstructure and Mechanical Properties of Ductile Iron Weldment Using Developed Coated Electrode
TL;DR: In this article, the effect of austempering temperature and time on the microstructural and mechanical properties of sound welded joints of ductile iron was studied. But, the results of tensile and charpy impact testing were not considered.
Journal ArticleDOI
Double-sided GTAW of nuclear grade steel: Mechanical and microstructure perspectives:
S. Mohan Kumar,N. Siva Shanmugam +1 more
TL;DR: In this article, the microstructural evolution and mechanical integrity of austenitic stainless steel SS321, a titanium stabilized nuclear grade mainly preferred for severe corrosive envirches, were investigated.
Journal ArticleDOI
Avaliação do efeito da energia de soldagem sobre as tensões residuais resultantes em juntas soldadas com multipasse
George Luiz Gomes de Oliveira,Thiago Ferreira da Silva,Hélio Cordeiro de Miranda,Marcelo Ferreira Motta +3 more
TL;DR: In this paper, the authors evaluated the effect of welding energy input, current and speed on the final residual stresses of a multipass joint in a semi-v chamfered structural steel and SMAW process.
Material Properties of Laser Powder Bed Fusion Processed 316L Stainless Steel
TL;DR: In this article, the laser powder bed fusion additive manufactured 316L stainless steel specimens were evaluated to establish a baseline for future research in determining an optimized energy density and build orientation, and the optimum energy density was determined to be 100 J/mm3, based on the highest transverse UTS, highest fatigue limit, moderate ductility, and moderate volume of lack of fusion defects.
