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
Analysis of macrosegregation near fusion boundary in fusion welding
TL;DR: In this article, a model is presented for the prediction of the post-solidification solute distribution of a single phase alloy in a fusion weld, taking into account the shape and size of the weld pool, the acceleration of growth rate as a solidifying crystal curves from the fusion boundary towards the weld centerline in an oval weld pool.
Dissertation
Laser Surface Modification of HVOF Coatings for Improvement of Corrosion and Wear Performance
TL;DR: In this paper, the effects of laser surface treatment on the corrosion and wear performance for Tribaloy 800 (T800), and T800-based WC HVOF-sprayed MMC coatings onto 316L stainless steel substrate were investigated.
Journal ArticleDOI
Properties of the Inconel 713 Alloy Within the High Temperature Brittleness Range
TL;DR: In this article, the results of thermal and mechanical tests performed on precision castings made of the Inconel 713C alloy and intended for use in the production of low pressure turbine blades are presented.
Weld Pool Simulations
TL;DR: In this article, the authors focused on the thermo and fluid dynamical phenomena occuring during a autogenous or non-autogenous arc fusion and its effect on the workpiece.
Journal ArticleDOI
Comparison of the Mechanical Properties of Hastelloy X Material after Welding by GTAW and Nd-YAG Laser
TL;DR: In this article, the authors compared Nd-YAG laser welding and traditional GTAW processes on Hastelloy X superalloy for comparison and found that traditional welding technology has better ultimate tensile strength and ductility.
