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.

Double sided arc welding of AA5182 aluminium alloy sheet
Y. Kwon,D. C. Weckman +1 more
TL;DR: The feasibility and merits of using the double sided arc welding (DSAW) process for making square welds in 1˙2 mm thick AA5182-O aluminium sheets in the butt-joint configuration for applications such as tailor welded blanks (TWB) has been studied.
Journal ArticleDOI
Effect of Nano Size TiO2 Particles on Mechanical Properties of AWS E 11018M Type Electrode
TL;DR: In this paper, nano-size particles of TiO2 were added to the coating of a shielded metal arc welding electrode (E 11018M) partially substituting the conventional micro size TiO 2 for possible enhanced electrode characteristics, which improved recovery of elements such as Mn, Ni, Mo, Ti etc.
Journal ArticleDOI
Tensile Properties and Fusion Zone Hardening for GMAW and MIEA Welds of a 7075-T651 Aluminum Alloy
TL;DR: In this paper, the tensile and hardness values for 7075-T651 aluminum alloy in the as welded and post weld heat treated conditions (solubilization and artificial aging-T6), obtained using GMAW and modified indirect electric arc (MIEA) welding processes are presented.
Journal ArticleDOI
A Novel Method for Resistance Plug Welding of 7075 Aluminum Alloy
TL;DR: In this paper, a novel resistance welding method, resistance plug welding (RPW), was used to weld 7075 aluminum alloy plates, which led to larger nugget diameters and higher peak loads and energy absorption in a RPW joint.
