Amit Kumar,Chandan Pandey +1 more
TL;DR: In this paper , the effect of the weld groove geometry on microstructure, mechanical behaviour, residual stresses and distortion of Alloy 617/P92 steel dissimilar metal weld (DMW) joints was examined.
Thermodynamic and solidification modeling of laser welded nickel-based alloys
TL;DR: In this paper, the authors present a review of the literature and literature review of this article.1 1.0 Introduction 2 2.0 Literature Review 5 2.1 2.
Journal ArticleDOI
Effect of N2- and CO2-Containing Shielding Gases on Composition Modification and Carbonitride Precipitation in Wire Arc Additive Manufactured Grade 91 Steel
TL;DR: In this paper , the effect of shielding gas composition on carbonitride precipitation in a 9 wt% Cr ferritic/martensitic (F/M) steel alloy known as Grade 91 was studied using N2 and CO2 gas additions to an inert Ar shielding gas atmosphere during wire arc AM.
Journal ArticleDOI
Theoretical Analysis for Solidification Cracking Susceptibility in Type 316FR Stainless Steel Laser Welds
TL;DR: For quantitative evaluation of solidification cracking susceptibility in two kinds of type 316FR stainless steel (316FR-A and 316FR-B) laser welds, laser beam welding transverse-Varestraint test was performed as discussed by the authors.
Universidade federal de santa catarina programa de pós-graduação em engenharia mecânica
TL;DR: It was verified that the control of the slope of gas plasma flow rate, current and travel speed is an important way to produce sound welds, specialy on closed track welds due to the impossibility of cut of the starting and the ending of the weld beads.

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.
