Prospects of pulsed current arc welding on aerospace grade Hastelloy X
TL;DR: The conventional constant current arc welding of Hastelloy X (Ni-Cr-Fe-Mo) leads to the solidification and liquation cracks in the weldment as discussed by the authors.
Characterization of powder and bulk Ti-6Al-4V samples produced by Electron Beam Melting process
TL;DR: In this article, diversi tipi di analisi, such as the test di scorrevolezza, the test of XRD, and the valutazione de the microstruttura sia tramite Microscopio Ottico (OM) integrato with Energy-Dispersive Spectroscopy (EDS), are evaluated.

The surface-tension-driven Benard conventions and unique sub-grain cellular microstructures in 316L steel selective laser melting
TL;DR: The unique sub-grain patterns have been found in some particular alloys (316L, Al-Si, Co-Cr-Mo) selective laser melting (SLM), the sub-micron-scale cellular, elongated cellular or even band structures are always coexisting inside one single macro-solidified grain this paper.
Journal ArticleDOI
Effects of ultrasonic pulsation of the welding current on the geometry of the fusion zone and heat-affected zone in submerged arc welding
TL;DR: In this paper, an arc ultrasonic excitation technique was used in the SAW process to evaluate the main parameters' influence associated with pulsed current on weld beads, such as the frequency and amplitude of ultrasonic current.

Modelling and Characterisation of the Texture Development in the Fusion Zone of an Austenitic Weld
Koenraad Decroos,Marc Seefeldt,Carsten Ohms,Roumen Petrov,Frederik Verhaeghe,Leo A.I. Kestens +5 more
TL;DR: In this article, the relation between texture and microstructure and the macroscopic solidification direction has been investigated for an austenitic 316L stainless steel weld, where the fusion zone has been characterised by EBSD.

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.
