Microstructure and Electrochemical Properties of CoCrCuFeNiNb High-Entropy Alloys Coatings
TL;DR: In this article, the microstructure and electrochemical behaviors of the CoCrCuFeNiNb high-entropy alloys coatings were investigated in detail, and the experimental results indicated that the coating consists of a simple fcc solid solution phase and an order (CoCr)Nb-type Laves phase.
Journal ArticleDOI
Microstructural Evolution and Mechanical Properties of Simulated Heat-Affected Zones in Cast Precipitation-Hardened Stainless Steels 17-4 and 13-8+Mo
Robert J. Hamlin,John N. DuPont +1 more
TL;DR: In this paper, the authors developed an understanding of microstructural evolution and resultant mechanical properties of cast precipitation-hardened (PH) stainless steels subjected to heat-affected zone (HAZ) thermal cycles in the solution treated and aged condition (S-A-W condition) and solution-treated condition with a postweld thermal cycle age (SW-A condition).
Journal ArticleDOI
Study on microstructure and properties of Fe-based amorphous composite coating by high-speed laser cladding
TL;DR: In this paper, Fe-Co-B-Si-Nb amorphous coatings were deposited on 45 medium carbon steel under different scanning speeds by high-speed laser cladding technology.
Journal ArticleDOI
Hot-wire GTAW cladding: inconel 625 on 347 stainless steel
TL;DR: In this paper, low-current gas tungsten arc welding (GTAW) cladding in the range of 60 to 100 A was performed with resistively heating hot-wire filler Inconel alloy (IN625) on the 347 stainless steel substrate.
Journal ArticleDOI
Effect of microstructure and chemical composition on cold crack susceptibility of high-strength weld metal
TL;DR: In this paper, the effects of the microstructural constituents, chemical composition, and retained austenite on high-strength weld metal were studied using preheat-free steels and GMAW solid wires with a low hydrogen content.

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.
