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.

Incipient Melting and Corrosion Properties of Friction Stir Welded AA2024 T3 Joints
TL;DR: The effect of welding speed on strength and corrosion behavior of FSW 2024-T3 joints was investigated in this article, where the authors found that higher welding speeds produced both a smaller hardness drop in the TMAZ/HAZ and a smaller width of the softened zone.
Journal ArticleDOI
Corrosion Behavior of Weathering Steel Q450NQR1 and Welded Metal using Flux-Cored Wire in 0.01 mol/L NaHSO3 Solution
TL;DR: In this paper, the microstructure of weld metal using flux-cored wire is mainly consisted of fine acicular ferrite and granular bainite, with some side plate ferrites and polygonal ferrite.
Journal ArticleDOI
Strength of Assembly Butt Joints of Plastic Pipes
TL;DR: In this article, the authors compared the tensile strength of welded and adhesive joints made of polypropylene pipes and found that welded joints obtained the highest average strength while the lowest strength was characteristic for the adhesive joints.
Journal ArticleDOI
Neutron strain scanning of fibre and diode laser welds in stainless steel and Ti6Al4V
TL;DR: In this article, the SALSA instrument at the Institut Laue Langevin (ILL) has been used to make neutron diffraction measurements for both fiber and diode laser welded stainless steel 304 and Ti6Al4V.
Dissertation
Etude de l’influence des écoulements dans le bain de fusion sur les mécanismes de solidification en soudage sur l'alliage Cu30Ni
TL;DR: In this paper, the authors present a contribution a la comprehension des couplages pouvant exister entre ecoulements and mecanismes de solidification, en relation avec les parametres de soudages.
