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.

Quality of dissimilar welded particle-reinforced TRIP/TWIP steels generated by electron beam braze-welding
Rudy Laubstein,Lars Halbauer,Stefan Martin,Volker Klemm,Rolf Zenker,Anja Buchwalder,Horst Biermann +6 more
TL;DR: In this article, electron beam brazing was used to join particle-reinforced steels by a dissimilar electron beam braze-welding with a beam offset.
Journal Article
An Analysis of the Role of Side Assisting Gas during CO2 Laser Welding
TL;DR: In this article, the role of side assisting gas during CO2 laser welding has been investigated, and it was found that side gas velocity can significantly affect the laser induced plasma and the weld cross-sectional geometry.
Microalloyed Steel Preforms
TL;DR: In this article, an analysis was conducted on two types of microalloyed steel to study their metallurgical, mechanical, and processing characteristics, and also to evaluate the suitability of utilizing these alloys as forgings for small gun tube components.
A quantitative method for optimizing weld overlay processing paramenters and comparing process performance
TL;DR: In this article, a study has been conducted to develop predictive methods for optimizing weld overlay processing parameters and comparing the performance of welding processes which are typically used in overlay applications, including arc efficiency, melting efficiency, deposition rate, dilution, and coating thickness.
Journal ArticleDOI
New t8/5 cooling time formula relating to welding quality
TL;DR: An overview of theoretical and practical results of welding steel tubes can be found in this paper, where two research groups are distinguished, one based on the application of welding modeling simulation packages, and the second dealing with extensive experimental studies that have the character of optimization of welding parameters.
