A Critical Assessment of First Principles Inputs for Modeling RIS in Austenitic Fe-Cr-Ni Steels
Radiation induced segregation (RIS) in austenitic Fe-Cr-Ni steels is a widely studied but incompletely understood process important for reactor components. Experimental studies have shown that Cr depletes strongly at grain boundaries, giving rise to corrosion resistance issues. Various research throughout the years has produced models that make specific assumptions about the dominant mechanisms...
متن کاملDevelopment of Alumina-Forming Austenitic Stainless Steels
This paper presents the results of the continued development of creep-resistant, alumina-forming austenitic (AFA) stainless steel alloys, which exhibit a unique combination of excellent oxidation resistance via protective alumina (Al2O3) scale formation and high-temperature creep strength through the formation of stable nano-scale MC carbides and intermetallic precipitates. Efforts in fiscal ye...
متن کاملEvaluation of corrosion behaviour on Mn-Cr austenitic steels using 0.1 M HCl solution
One of the attractive low activation steels is the austenitic Mn-Cr steel from the view point of waste disposal because of few long-lived nuclides. In this paper, three types of Mn-Cr austenitic steels were fabricated by vacuum induction furnace. Then plates with 10 mm thickness were fabricated by hot-rolling. The physical metallurgy of these steels was studied by the corrected Schaeffler diagr...
متن کاملPHASE STABILITY AND SEMICONDUCTING BEHAVIOUR OF LOW ACTIVATION AUSTENITIC MN-CR STEELS
Four compositions of austenitic Mn-Cr steels have been developed successfully for in-vessel component materials in power plant industry. The phase stability of these Mn-Cr steels was studied by and X-ray diffraction (XRD) patterns. XRD patterns have shown that the matrix of these Mn-Cr steels is a single γ-phase structure. The potentiodynamic polarisation curves suggested that these fabricated ...
متن کاملLow-Temperature Carburization of Austenitic Stainless Steels
LOW-TEMPERATURE CARBURIZATION is a gaseous carburization process performed at atmospheric pressure, at temperatures where the kinetics of substitutional diffusion are very slow. Low-temperature carburization hardens the surface of austenitic stainless steels through the diffusion of interstitial carbon, without the formation of carbides. The surface must be activated, by modification and remova...
