TLDR
In this paper, a comparison of a range of commercial and model alloys, conventional austenitic steels do not have sufficient oxidation resistance with only ∼18Cr-10Ni, and higher alloyed type 310 stainless steel is protective but Ni is not a desirable alloy addition for this application.About:

Microstructural control of FeCrAl alloys using Mo and Nb additions
TL;DR: The effects of Mo and Nb additions on the microstructure and mechanical properties of two FeCrAl alloys were studied in this article, where fine and uniform recrystallized grain structures were achieved in both alloys through suitable annealing after warm-rolling.
Journal ArticleDOI
Microstructural stability of Fe–Cr–Al alloys at 450–550 °C
TL;DR: In this paper, a Kinetic Monte Carlo (KMC) model of the Fe-Cr-Al system was developed, and the developed KMC model yielded results in good agreement with the experimental data.

Performance of iron-chromium-aluminum alloy surface coatings on Zircaloy 2 under high-temperature steam and normal BWR operating conditions
TL;DR: In this paper, an autoclave testing of FeCrAl-coated Zircaloy 2 (Zy2) coupons under pressure-temperature-dissolved oxygen coolant conditions representative of a boiling water reactor (BWR) environment has been performed.
Journal ArticleDOI
Effect of steam on high temperature oxidation behaviour of alumina-forming alloys
TL;DR: In this paper, a critical Cr-Al composition was identified for 1 bar isothermal steam (100% H2O) oxidation resistance at 1200°C, which differed for exposures in Ar-50%H2O at the same temperature.
Journal ArticleDOI
Effect of Al and Cr Content on Air and Steam Oxidation of FeCrAl Alloys and Commercial APMT Alloy
TL;DR: In this paper, the authors evaluated short-term (4h) oxidation resistance in steam and air at 1200-1475°C and found a synergistic effect between the Cr and Al contents to enable Al2O3 formation under these conditions.

Experimental observations in support of the dynamic-segregation theory to explain the reactive-element effect
TL;DR: In this article, a model was developed to explain the effects associated with the addition of reactive elements that is based on the segregation of reactive-element ions to scale grain boundaries and the metal-oxide interface.
Journal ArticleDOI
Structural materials challenges for advanced reactor systems
TL;DR: In this paper, the authors give a brief overview of various materials that are essential to establish advanced systems feasibility and performance for in pile and out of pile applications, such as ferritic/martensitic steels (9-12% Cr), nickel based alloys (Haynes 230, Inconel 617, etc.), oxide dispersion strengthened ferritic and martensite steels, and ceramics (SiC, TiC, etc.).

Oxide dispersion-strengthened steels: A comparison of some commercial and experimental alloys
TL;DR: In this article, the differences and similarities of different ODS steels are explained in terms of the microstructures of the steels, and observations are explained using the properties of the ODS micro-structures.
Journal ArticleDOI
Paralinear Oxidation of CVD SiC in Water Vapor
TL;DR: In this article, the long-term degradation rate of CVD SiC is determined by the volatility of the silica scale, which is observed as the water vapor oxidized the SiC and simultaneously volatilized the scale.
Journal ArticleDOI
The Effect of Oxide Volatilization on the Oxidation Kinetics of Cr and Fe‐Cr Alloys
TL;DR: In this paper, the authors derived equations which describe the oxidation behavior of a system in which both diffusive and gas/oxide interface processes occur simultaneously, and applied these equations to the oxidation of Cr and Fe-Cr alloys.
