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.

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.

Microstructure Evolution and Mechanical Properties Investigation of Al-6 %Cu Alloy Laser and GTA Welds
TL;DR: In this paper, microstructural development, post-weld ageing response and mechanical properties of gas tungsten arc and CO2 laser welded Al-6 %Cu (AA2219) alloy were investigated.
Journal ArticleDOI
Prediction of Solidification Cracking by In-situ Observation and 3D FEM-Analysis
TL;DR: In this paper, a method for predicting solidification cracking during laser welding by accurately obtaining the high temperature ductility and weld strain of weld metal was developed, where the U-type hot cracking behavior was in-situ observed by a high speed camera so that the critical strain for the initiation of solidification crack was measured precisely.
Impact of voltage on austentic stainless steel for the process of tig and mig welding
TL;DR: In this article, the mechanical properties of austentic stainless steel for the process of TIG and MIG welding are discussed. And the voltage is taken constant and various characteristics such as strength, hardness, ductility, grain structure, modulus of elasticity, tensile strength breaking point, HAZ are observed in two processes and analyzed and finally concluded.

Welding Parameters and their Influence on the Abrasion Resistance of Structural Steels at Elevated Temperatures
TL;DR: In this article, the role of interpass temperature and heat input on the hot hardness and wear behavior of welded structural steels was investigated and the influence of different microstructural parameters such as phase content, processing and the resulting temperature-hardness coherence on the wear resistance were evaluated within a high temperature abrasion test and a hot hardness test rig.
