Journal ArticleDOI
Open-source wire and arc additive manufacturing system: formability, microstructures, and mechanical properties
TL;DR: In this article, a metal wire and arc additive manufacturing (WAAM) system was designed and evaluated from the three aspects of formability, microstructures, and mechanical properties, and the results indicated that the formability of metal parts fabricated by the open-source WAAM system was improved by using compulsory cooling solution.
Journal ArticleDOI
Mechanical and tribological behaviors of Ti-DLC films deposited on 304 stainless steel: Exploration with Ti doping from micro to macro
TL;DR: In this paper, the evolution of microstructure, mechanical and tribological behaviors of diamond-like carbon (DLC) and Ti-DLC films were systematically investigated, and the wear mechanism of the films with different Ti doping stages was also contrastively discussed.
Journal ArticleDOI
Optimization on mechanical properties of Fe7−xCrxC3 carbides by first-principles investigation
TL;DR: In this paper, a serious investigation of Fe7−xCr3C3 carbides was performed based on first-principles calculations, which showed that Fe4Cr 3C3 is potentially a high strength and hard material, possessing a ductile property interestingly as well.
Journal ArticleDOI
Fe-24 wt.%Cr-4.1 wt.%C hardfacing alloy: Microstructure and carbide refinement mechanisms with ceria additive
TL;DR: In this article, the microstructure and carbide refinement mechanisms of Fe-Cr-C hardfacing alloys with 0, 1.5, and 4.1% ceria additives have been systematically investigated.
Journal ArticleDOI
Experiments and calculations on refining mechanism of NbC on primary M7C3 carbide in hypereutectic Fe-Cr-C alloy
TL;DR: In this paper, two hypereutectic Fe-Cr-C hardfacing alloys were manufactured, whose Nb contents are 0 and 1.2% respectively, and their phase precipitation curves were calculated by Thermal-calc software, which indicated that NbC precipitates previously to the nucleation of primary M 7 C 3 carbide.
