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.

Fabrication of ultrafine grained FeCrAl-0.6 wt.% ZrC alloys with enhanced mechanical properties by spark plasma sintering

TL;DR: In this paper, the effect of milling speed on powder characteristics, microstructure and mechanical properties of FeCrAl alloys were investigated, and the results demonstrated that the excellent mechanical properties were not only attributed to the dispersion strengthen by nanosized ZrC, but also the ultra-fine grained structure induced by the milling process.
Journal ArticleDOI

Failure probabilities of SiC clad fuel during a LOCA in public acceptable simple SMR (PASS)

TL;DR: In this paper, the structural integrity of SiC clad fuels in reference Small Modular Reactors (SMRs) (NuScale, SMART, IRIS) and a commercial pressurized water reactor (PWR) are assessed with a multi-layered SiC cladding structural analysis code.
Journal ArticleDOI

High-temperature oxidation of advanced FeCrNi alloy in steam environments

TL;DR: In this article, the evolution and structure of oxide layer formed in steam environments were characterized using X-ray diffraction, hard x-ray photoelectron spectroscopy, Xray fluorescence methods and scanning electron microscopy, demonstrating that a compact and continuous oxide scale was formed consisting of two layers, chromium oxide and spinel phase (FeCr2O4) oxides.

Influence of Ta/Zr minor-alloying on the high-temperature microstructural stability of cladding Fe–Cr–Al ferritic stainless steels

TL;DR: In this paper, the influence of Ta and Zr minor-additions on the microstructural stabilities at high temperatures (HTs) of Fe-Cr-Al-Mo-Nb alloys was investigated systematically.

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.

Structural materials challenges for advanced reactor systems

P. Yvon, +1 more
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.
