Effect of Mechanical Arc Oscillation on the Grain Structure of Mild Steel Weld Metal
TL;DR: The effect of mechanical arc oscillation on the weld metal grain structure in mild steel gas tungsten arc welds has been studied in this paper, showing that the strength of welds made with arc oscillations was higher than those made without arc oscillators.
Journal ArticleDOI
Microstructure and pitting corrosion of similar and dissimilar stainless steel welds
G. M. Reddy,K. S. Rao,T. Sekhar +2 more
TL;DR: In this article, electron beam and friction welds have been compared to determine the mechanism of corrosion behavior of similar and dissimilar metal welds of three classes of stainless steels, namely, AISI 304, FISI 430 and duplex stainless steel (AISI 2205).
Journal ArticleDOI
Microstructure and mechanical behavior of PH 13–8Mo martensitic stainless steel fabricated by wire arc additive manufacturing
TL;DR: In this paper, a wire arc additive manufacturing (WAAM) was applied to fabricate precipitation hardened (PH) 13-8Mo martensitic stainless steel parts for applications in injection molding equipment, aerospace components, and marine.
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.
