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.

Journal ArticleDOI
Solute convection effects on a bubble entrapped as a pore during unidirectional upward solidification
TL;DR: In this paper, a transport model is proposed to predict entrapment of a bubble during unidirectional upward solidification, which shows that strong convection deflects the pore growth toward the downstream direction.
Journal ArticleDOI
Study of solidification behaviour and mechanical properties of arc stud welded AISI 316L stainless steel
TL;DR: In this paper, the impact of welding current and time on the microstructure and mechanical properties of AISI 316L stud/plate joint was investigated using optical microscope and scanning electron microscope (SEM).
Journal ArticleDOI
Corrosion Resistance Behavior of GTAW Welded AISI type 304L Stainless Steel
TL;DR: In this paper, the microstructural evolutions of type 304L SS gas tungsten arc welded (GTAW) joint of different thickness were investigated using optical microscopy, scanning electron microscopy and X-ray diffraction, micro-Vickers hardness test and electrochemical techniques.
Journal ArticleDOI
Modelling of Gas Tungsten Arc Welding Pool under Marangoni Convection
TL;DR: In this article, a two-dimensional simulation model was developed to study the physics of gas tungsten arc welding (GTAW) processes, and experimental spot-welds on Ti-5Al-5Mo-5V-3Cr was carried out to compare to the model for crucial clues such as, the magnitude of Marangoni convectional stress that is difficult to determine experimentally; and to estimate the enhancement factor, an artificial parameter incorporated into the model proven to account for any discrepancies between simulated results and experimental weld pool shapes, due to lack

Root cause analysis of a failure in a flange-pipe welded joint in a steam line in an ammonia plant: Experimental investigation and simulation assessment
TL;DR: The root cause of failure in an ASTM A106 pipe-ASTM A105 flange welded joint, welded to a pump in an ammonia plant, was investigated in this paper.
