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.

Ductile Fracture of 13% Cr-4% Ni Martensitic Stainless Steels Used in Hydraulic Turbine Welded Runners
TL;DR: In this paper, the authors defined a critical value for the existence of cracks in a turbine runner under cycline fatigue in loading lifetime, which is defined as the ratio of the length of a fracture to its length.
Journal ArticleDOI
Microstructural administered mechanical properties and corrosion behaviour of wire plus arc additive manufactured SS 321 plate
S. Mohan Kumar,R Sasikumar,A. Rajesh Kannan,R. Pramod,N. Pravin Kumar,N. Siva Shanmugam,M. Vishnukumar +6 more
TL;DR: In this paper, wire plus arc additive manufacturing (WAAM) technology with higher deposition rate and efficient material utilization was employed to fabricate a stainless steel 321 (SS 321) wall for the first time.
Journal Article
Characterization of Submerged-Arc Welds From the World Trade Center Towers: As-Deposited Welds and Failures Associated With Impact Damage of the Exterior Columns
TL;DR: In this article, the authors evaluated the impact-damaged welds from the World Trade Center towers and found that failure occurred in this region due to the lower cross-sectional area of the plate and the degraded HAZ mechanical properties (i.e., ductility, toughness with respect to the base plate).
Journal ArticleDOI
The Segregation and Liquation Crackings in the HAZ of Multipass Laser-Welded Joints for Nuclear Power Plants
TL;DR: In this article, the authors investigated the segregation and liquation crackings in the heat-affected zone (HAZ) beside Inconel 52M overlays of multipass laser-welded joints for nuclear power plants.
Journal ArticleDOI
Artificial Neural Network application to the friction welding of AISI 316 and Ck 45 steels
Ismail Ersozlu,Sare Çelik +1 more
TL;DR: In this article, an Artificial Neural Network (ANN) model is developed for the analysis of the correlation between the friction welding parameters and tensile strength of both AISI 316 austenitic-stainless steel and Ck 45 steel.
