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).
F. A. Oyawale,K. O. Sanusi +1 more
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.

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.

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.

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.
