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.

Influence of the anode and wehnelt voltage on the crossover position in the electron beam welding
TL;DR: In this paper, the influence of the wehnelt voltage anode voltage on the crossover position of the electron beam welding (EBW) was monitored and analyzed through the numerical modelling methods.
Journal Article
Comparative Evaluation of Flux Coated Mild Steel Electrodes in Nigeria
TL;DR: In this article, a comparative evaluation on the brands of flux coated mild steel electrodes available in the Nigerian market is presented, where the results obtained showed the percentage compositions of the weldment constituents, micrographs and values of tensile strength of adhesion as well as the hardness tests.
Additive Manufacturing of L12 Precipitate Strengthened Nickel and Aluminum Alloys
TL;DR: In this paper, a Ni-base superalloy was used for micro-cracking mitigation and a new alloy was developed to reduce the solidification interval of CM247LC.
Microstructural Analysis of Laser Cladding of Stellite 6 on Ductile Iron
TL;DR: In this paper, a low power pulsed Nd:YAG laser was used to deposit a stellite 6 alloy in the form of powder on a ductile cast iron substrate.
Journal ArticleDOI
Computational and experimental observations of welds in third-generation nickel-based superalloys
TL;DR: In this paper, the weld quantitative solidification paths in the newly designed third-generation superalloys were analyzed using both computational and experimental approaches, and the results of the model demonstrated that these were very close to unity for austenite former elements, i.e. Ni, Co, Cr and Fe.
