Journal ArticleDOI
The Effect of the Hyperstoichiometric Ti/N Ratio Due to Excessive Ti on the Toughness of N-Controlled Novel Fire- and Seismic-Resistant Steels
TL;DR: In this paper, the authors investigated the toughness of the base material and the coarse-grain heat-affected zone (CGHAZ) of N-controlled fire-and seismic-resistant (FSR) steels.
Journal Article
Study of the Mechanical and Metallurgical Properties of Dissimilar Welds
TL;DR: In this article, the authors used shielded metal arc welding (SMAW) for dissimilar welds made of low carbon steel (A516) and austenitic stainless steel (316L) by SMAW and with different electrodes (E7018, E6013, E309L, E308L).
Journal ArticleDOI
Parametric Optimization of Submerged ARC Welding Using L9 Orthogonal Array
TL;DR: In this paper, Taguchi's L9 orthogonal array is used to find out the appropriate process conditions to obtain quality submerged arc welded components with typical applications, and it is found out that at a weld current of 400 A, welding speed of 450 mm/min and with flux with basicity index of 1.2, desired weld deposition can be obtained.
Journal ArticleDOI
Novel Degradation Mechanism of a Structural Wire Rope During Its Life Cycle
TL;DR: In this article, a failure analysis of a wire rope used in a basic oxygen furnace (BOF) was carried out, showing that the wire rope suffered premature damage due to improper lubrication during service that led to direct metal-to-metal contact, associated friction, abrasion and fusion of wires.

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.
