Weldability testing of dissimilar combinations of 5000- and 6000-series aluminum alloys
M. M. Mossman,J. C. Lippold +1 more
TL;DR: In this paper, similar and dissimilar combinations of alloys 6111-T4, 6022-T 4, 5182-H16, and 5754-O were evaluated using gas tungsten arc welding in conjunction with the Sigmajig weldability test.
Journal ArticleDOI
Modeling of Grain Structure and Heat-Affected Zone in Laser Surface Melting Process
TL;DR: In this paper, a combination of phase field and cellular automata methods is used to study the effect of initial grain size and laser power density on heat-affected zone (HAZ) formation during laser surface melting.
Journal ArticleDOI
Developing new microstructure through laser melting of electrospark layer of precipitation hardened nickel based superalloy
TL;DR: In this article, a high-oriented fine microstructure was achieved through laser melting of electrospark layer of a precipitation hardened nickel based superalloy using electron back scattered diffraction analysis, it was found that the new layer has preferred orientation toward the surface.

Mechanical and metallurgical investigation on gas metal arc welding of super austenitic stainless steel
TL;DR: In this article, the microstructure and mechanical properties of super austenitic stainless steel butt joints made by gas metal arc welding with different shielding gas mixtures were investigated under two sets of optimized parameters employing three different shielding gases.
Journal ArticleDOI
Post-weld Heat Treatment and Groove Angles Affect the Mechanical Properties of T92/Super 304H Dissimilar Steel Weld Joints
TL;DR: In this paper, the microstructures and mechanical properties of dissimilar weld joints between T92 and Super 304H steels were investigated, and the optimal groove angle for T92/Super 304H dissimilar joints was found to be 20°, considering mechanical properties.

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.
