Mechanical properties improvement of thick multi-pass weld by layered ultrasonic impact treatment
TL;DR: In this article, the effects of layered ultrasonic impact treatment (LUIT) on the mechanical properties of thick multi-pass weld were investigated, and the results show that LUIT can increase the strength of weld metal, resulting in more uniform shear strength distribution across the treated WM and higher impact toughness of the WM.

Influence of Plasma Remelting on the Microstructure and Cavitation Resistance of Arc-Sprayed Fe-Mn-Cr-Si Alloy
Anderson Geraldo Marenda Pukasiewicz,P. R. C. Alcover,A. R. Capra,Ramón Sigifredo Cortés Paredes +3 more
TL;DR: In this paper, an Fe-Mn-Cr-Si alloy was deposited by arc spraying and then remelted by a plasma-transferred arc process, and the influence of remelting current on coating and base metal microstructure and cavitation resistance was studied.

Active flux tungsten inert gas welding of austenitic stainless steel AISI 304
TL;DR: In this article, the effects of flux assisted tungsten inert gas (A-TIG) welding of 4 (10) mm thick austenitic stainless steel EN X5CrNi1810 (AISI 304) in the butt joint were investigated.
Journal ArticleDOI
Study of 6 mil Cu Wire Replacing 10–15 mil Al Wire for Maximizing Wire-Bonding Process on Power ICs
TL;DR: In this article, the experimental study of using 6-mil Cu wire on an ASM wire bonder to replace 10-15 mil Al wire in a power IC device was discussed.
Journal ArticleDOI
High-pressure rolling of low-carbon steel weld seams: Part 1 - Effects on mechanical properties and microstructure
TL;DR: In this paper, a variety of experimental techniques, including microhardness measurements and cross-weld tensile tests with digital image correlation, have been used to characterise the effects of rolling on the mechanical properties and microstructure of the weld material in welded structural steel specimens.

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.
