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.

Effect of welding consumables on hydrogen induced cracking of armour grade quenched and tempered steel welds
TL;DR: In this paper, an attempt has been made to study the effect of welding consumables on hydrogen induced cracking of Q&T steel welds by implant testing, which has been used for making welds using three different consumables, namely austenitic stainless steel, low hydrogen ferritic steel (LHF), and high nickel steel (HNS).
Journal ArticleDOI
Laser Welding of Titanium and Dental Precious Alloys
TL;DR: In this paper, the performance of laser welding of Ti and two dental precious alloys (Ag-Pd-Au, Au-Pt-Ag) was investigated by mechanical testing and microscopic observation, using butt joint as design.
Journal ArticleDOI
Influence of Gd and B on solidification behaviour and weldability of Ni–Cr–Mo alloy
TL;DR: The influence of Gd and B on the solidification behavior and weldability of Ni-Cr-Mo alloy UNS N06455 has been investigated by Varestraint testing, differential thermal analysis and microstructural characterisation as discussed by the authors.
Journal ArticleDOI

Babak Mehrjou,Reza Soltani,Mahmoud Heydarzadeh Sohi,Mohammad Javad Torkamany,Zia Valefi,Hassan Ghorbani +5 more
TL;DR: In this paper, the surface of AZ91 magnesium alloy plasma sprayed with WC-12 ¾wt-%Co powder was melted by pulsed Nd:YAG laser.
Journal ArticleDOI
Hot cracking in autogenous welding of 6061-T6 aluminum alloy by rectangular pulsed Nd:YAG laser beam
TL;DR: In this article, the effect of pulsed Nd:YAG laser parameters and preheating on the creation of hot cracks in the 6061-T6 aluminum alloy was investigated.
