Journal ArticleDOI
Microstructural evolution and mechanical properties of a low-carbon low-alloy steel produced by wire arc additive manufacturing
TL;DR: In this article, a wire arc additive manufacturing (WAAM) method was used to fabricate a low carbon low-alloy steel wall using a gas metal arc welding (GMAW) torch translated by six-axis robotic arm.
Journal ArticleDOI
Comparison of microstructural characteristics and mechanical properties of shipbuilding steel plates fabricated by conventional rolling versus wire arc additive manufacturing
TL;DR: In this article, the fabrication feasibility of a conventionally rolled low-carbon low-alloy shipbuilding steel plate (EH36) by emerging wire arc additive manufacturing (WAAM) technology using ER70S feedstock wire was investigated.
Journal ArticleDOI
Effect of Solidification Defects and HAZ Softening on the Anisotropic Mechanical Properties of a Wire Arc Additive-Manufactured Low-Carbon Low-Alloy Steel Part
TL;DR: In this paper, the effects of solidification defects on the anisotropic mechanical properties of a low-carbon low-alloy steel (ER70S-6) wall produced by wire arc additive manufacturing (WAAM) have been investigated.
Journal ArticleDOI
Microstructure and mechanical behavior of PH 13–8Mo martensitic stainless steel fabricated by wire arc additive manufacturing
TL;DR: In this paper, a wire arc additive manufacturing (WAAM) was applied to fabricate precipitation hardened (PH) 13-8Mo martensitic stainless steel parts for applications in injection molding equipment, aerospace components, and marine.
Journal ArticleDOI
On the Post-Printing Heat Treatment of a Wire Arc Additively Manufactured ER70S Part.
TL;DR: Wire arc additive manufacturing (WAAM) is known to induce a considerable microstructural inhomogeneity and anisotropy in mechanical properties, which can potentially be minimized by adopting appropriate post-printing heat treatment, but the effects of two heat treatment cycles, including hardening and normalizing on the microstructure and mechanical properties are studied.
