Effects of chromium on the microstructure and inclusions of multipass low alloy steels weld metal in shielded metal arc welding

TL;DR: In this paper, the effect of chromium content on the microstructure and inclusions formation in low alloy steel multipass welds was investigated and the results showed an increase in acicular ferrite formed at the expense of primary ferrite and ferrite with second phase with steady refinement of microstructures.

Investigation of the Grain Structure of the Fusion Zone of Single Pass Arc Welding of Structural Steel (NST 34 L-C).

TL;DR: In this paper, the grain structure of the fusion zone of a single pass arc welding of structural steel was investigated to identify the mode of growth and grain transition of the zone and adjacent weld.

Investigation of microstructures and mechanical properties of dissimilar welds between Incoloy 825 and 316 stainless steel

TL;DR: In this article, microstructural features and mechanical properties of Incoloy 825-316L stainless steel dissimilar joints have been investigated using pulsed gas tungsten arc welding method.

A modular framework to obtain representative microstructural cells of additively manufactured parts

TL;DR: In this paper , a general microstructural mapping procedure is presented to map and average different micro-structural features inside the representative cell and an extension of the method is proposed to recover a representative cell with a periodic shape as required for subsequent numerical micromechanical simulations under periodic boundary conditions.

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

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.
