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
Process-Dependent Composition, Microstructure, and Printability of Al-Zn-Mg and Al-Zn-Mg-Sc-Zr Alloys Manufactured by Laser Powder Bed Fusion
TL;DR: In this paper, the microstructure of Al-Zn-Mg-Sc-Zr alloys was investigated and the Scheil-Gulliver non-equilibrium solidification calculations showed that the AlZnMg alloys with lower Zn and Mg concentrations had smaller solidification range and steepness values (i.e., ΔT) and corresponded to a lower cracking severity.
Journal ArticleDOI
Friction stir welding of hypereutectoid steel (SK5) below eutectoid temperature
TL;DR: In this paper, the welded joints of the hypereutectoid steel (SK5, AISI-SAE W1-8), which is a high carbon steel with 0·85 wt-%C, were studied by friction stir welding below and above the A1 point.
Journal ArticleDOI
Structural integrity of additively manufactured aluminum alloys: Effects of build orientation on microstructure, porosity, and fatigue behavior
TL;DR: In this paper, the microstructure, porosity, and fatigue behavior of five different contemporary aluminum alloys fabricated via a laser beam powder bed fusion (LB-PBF) AM process were investigated.
Journal ArticleDOI
Experimental investigation on Ytterbium fiber laser butt welding of Inconel 625 and Duplex stainless steel 2205 thin sheets
TL;DR: In this paper, welding of Super Alloy Inconel 625 and duplex stainless steel 2205 (DSS 2205) has been successfully performed through Ytterbium fiber laser at different heat inputs.
Journal ArticleDOI
