Journal ArticleDOI
Characterization of NiCrAlC PTA coatings
TL;DR: In this paper, the results show that the aluminide compounds were stable, the coatings that solidified more slowly having the highest hardness after temperature exposure and potentially being suitable for use in high-temperature abrasion environments.
Journal ArticleDOI
The impact of Adjustable-Ring-Mode (ARM) laser beam on the microstructure and mechanical performance in remote laser welding of high strength aluminium alloys
TL;DR: In this paper , the use of an adjustable-ring-mode (ARM) laser beam was introduced to optimize the microstructure and mechanical performance of laser welded 6xxx high-strength aluminium alloy joints.
Journal ArticleDOI
Digitisation of metal AM for part microstructure and property control
Merve Doğu,Éanna McCarthy,Ronán McCann,Vivek Mahato,Antonella Caputo,Markus Bambach,Inam Ul Ahad,Dermot Brabazon +7 more
TL;DR: In this paper , the state-of-the-art in the control of part properties in AM is examined, including the effect of microstructure on part properties, and an outlook is presented with a view towards potential avenues for further research required in the field of metal AM.

Mitigation of micro-cracks in dissimilar welding of Inconel 718 and austenitic stainless steel
A. K. Sahu,Swarup Bag,Ke Huang +2 more
TL;DR: Inconel 718 and SS316L stainless steel has been shown to suffer from solidification cracking in the welded structure by solute segregation during dissimilar welding.

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.
