Journal ArticleDOI
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
Design Guideline for Intermetallic Compound Mitigation in Al-Mg Dissimilar Welding through Addition of Interlayer
TL;DR: In this paper, a 3-step design guideline in Al-Mg dissimilar welding through addition of an interlayer and a case study of using pure Ni foil as a proof of concept is presented.
Journal ArticleDOI
Effect of preweld microstructure on HAZ liquation cracking of Rene 80 superalloy
TL;DR: In this article, the microstructure of as cast, solution treated and overaged Rene 80 superalloy before and after welding treatment was studied and the formation of HAZ liquation cracking or microfissuring was found to be strongly dependent on the constitutional liquation of grain boundary precipitates.
Journal ArticleDOI
Microstructure and properties of a dissimilar weld between alloy 617 and A387 steel using different filler metals
TL;DR: In this article, microstructural and mechanical properties of a (butt) weld, joining two base metal alloys 617 and A387-Gr.11 steel, were investigated.
Journal ArticleDOI
Solidification crack initiation and propagation in pulsed laser welding of wrought heat treatable aluminium alloy
TL;DR: In this article, the effect of preheating on strain rate and liquid flow rate is analyzed to develop a model for solidification cracking in successive laser weld spots in 2024 aluminium alloy.
Journal ArticleDOI
Characterization of Tungsten Inert Gas (TIG) Welding Fume Generated by Apprentice Welders
Halshka Graczyk,Nastassja Lewinski,Nastassja Lewinski,Jiayuan Zhao,Nicolas Concha-Lozano,Michael Riediker +5 more
TL;DR: It is recommended that future exposure assessments take into consideration welding performance as a potential exposure modifier for apprentice welders or welders with minimal training.
