Mechanism of grain refining in AZ91 Mg welds by arc oscillation
TL;DR: In this article, a study was conducted to study grain refining in gas-to-tungsten arc welding of AZ91 Mg, focusing on identifying the mechanism of grain refining.
Journal ArticleDOI
Effect of energy density on the interface evolution of stainless steel 316L deposited upon INC 625 via directed energy deposition
TL;DR: In this paper, the effect of input energy density on the evolution of the dissimilar metal interface and its mechanical properties was explored by varying the laser power for each build, and it was seen that high energy deposition resulted in a measurable, remelted layer solute (RLS) fraction that comprised each deposited layer, creating a stepwise-graded interface.
Journal ArticleDOI
Evaluation of Ni–Al coatings processed by plasma transferred arc
TL;DR: In this article, the microstructure of Ni aluminides was investigated in situ by plasma transferred arc (PTA) welding and the results validated the potential of PTA hardfacing as a processing technique for surface tailoring.
Journal ArticleDOI
Effect of quality control parameter variations on the fatigue performance of aluminum friction stir welded joints
TL;DR: In this article, the authors performed fatigue tests on 6061-T651 and 5083-H321 aluminum friction stir welded joints with dimensions and loading conditions typical for structural applications.

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.
