Corrosion of Fe-25Cr-20Ni-0.40C alloy: an experimental and computational study
(IJRAET, 2016-01)
The investigation combines microstructura l characterization analyses and atomistic modeling to elucidate the mechanism of carburization embrittlement of an iron-nickel-chromium alloy expo sed to high temperature. It was ...
Stability of expanded austenite, generated by ion carburizing and ion nitriding of AISI 316L SS, under high temperature and high energy pulsed ion beam irradiation
(Elsevier, 2013-02)
Expanded austenite can be generated on austenitic stainless steels either by ion carburizing or ion nitriding. In both cases the resulting fcc crystal structure, supersaturated with nitrogen or carbon, is strongly hardened ...

Efeito da variação do fluxo de metano e nitrogênio na cementação a plasma a baixa temperatura de ferro puro sinterizado
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2016-11-11)
Low temperature plasma carburizing is a surface thermochemical treatment commonly performed on stainless steels as it prevents the sensitization phenomenon when compared to carburizing at high temperatures. Other advantages ...
Characterization of expanded austenite developed on AISI 316L stainless steel by plasma carburization
(Elsevier Science Sa, 2010-04)
Expanded austenite generation through ion carburizing of AISI 316L using two different reactive gas mixtures (Ar 50%, H2 45%, CH4 5% and Ar 80%, H2 15%, CH4 5%) has been studied. It was found that an 14 µm surface layer ...
Microstructural evolution of a modified HP alloy: experimental and complementary computational study
(Council for Innovative Resarch, 2017-12)
We present results of the microstructural characterization of austenitic stainless steel (HP series) modified with Nb, aged at temperatures of 750, 800, 850, 900 and 950oC in air at different times. Microstructural changes ...
