Title: Effects of carbonitrides and carbides on microstructure and properties of castable nanostructured alloys

Abstract

In this work, to develop advanced reduced-activation ferritic-martensitic (RAFM) steels for fusion reactor structural applications, both carbonitride- and carbide-strengthened castable nanostructured alloys (CNAs) were explored for higher densities of MX (M = Ti/Ta/V/etc. and X = C/N) nanoprecipitates. Additionally, systematic comparisons between the two types of CNAs indicated generally similar microstructures and comparable tensile properties and creep resistance. However, the carbide-CNAs did show some advantages over the carbonitride-CNAs in terms of the uniformly distributed higher density of MC nanoprecipitates, greater Charpy impact upper shelf energies, less deuterium retention and swelling, and potentially less transmutation-induced composition changes and consequently thermodynamically more stable carbides. The carbide-CNAs showed the best-balanced high performance in the examined properties, in contrast to the significantly varied performance of oxide-dispersion-strengthened alloys and the generally lower performance of current RAFM steels.

Radiological analysis and transmutation calculation of representative castable nanostructured alloys

Journal Article Zhong, Weicheng ; Tan, Lizhen - Fusion Engineering and Design

In this work, radiological analysis regarding the waste management was performed on two current reduced-activation ferritic-martensitic (RAFM) steels Eurofer 97 and F82H and two castable nanostructured alloys (CNAs) CNA1 and CNA3 using the European DEMO first wall spectrum. CNA1 and CNA3 are a new generation of RAFM steels, which have increased amounts of nanoscale carbonitrides and carbides precipitates, respectively, via small composition modifications. Furthermore, the increased nitrogen in CNA1 leads to higher activity at ≥50 years, and thus to the disposal concern under the current NRC regulation. However, the calculation using Fetter’s evaluation leads to reduced waste disposal rating (WDR)more »« less

Development of castable nanostructured alloys as a new generation RAFM steels

Journal Article Tan, Lizhen ; Katoh, Yutai ; Snead, Lance L. - Journal of Nuclear Materials

Castable nanostructured alloys (CNAs) are being developed as a new generation of reduced-activation ferritic-martensitic (RAFM) steels to overcome certain limitations of the current RAFM steels, such as their narrow operating temperature range and associated low strength at high temperatures. Six CNAs were developed and examined, exhibiting noticeably increased yield strength, tensile strength and creep resistance as compared to the current RAFM steels, which are comparable to ODS-Eurofer (0.3% Y₂O₃) at 650 °C. The enhanced strength of CNAs is also associated with a beneficial increase in Charpy impact upper-shelf energies, up to ~2.5 times that of the current RAFM steels, withmore »« less

Microstructure and property tailoring of castable nanostructured alloys through thermomechanical treatments

Journal Article Tan, Lizhen ; Parish, Chad M. ; Hu, Xunxiang - Journal of Nuclear Materials

Three types of microstructures, i.e., tempered-martensite (TM), ferrite (F), and dual-phase (TM + F), were developed in a castable nanostructured alloy that favors a high density of nanoprecipitates compared with the precipitates in current reduced-activation ferritic-martensitic steels. The effect of the distinct microstructures on tensile properties, Charpy impact toughness, and thermal helium desorption behavior was investigated with the full TM structure as a reference. The results indicated that the F domain in the TM + F structure governed the strength and slightly impaired the impact toughness. The full F structure exhibited the highest strength without compromising ductility, but it noticeablymore »« less

Recent status and improvement of reduced-activation ferritic-martensitic steels for high-temperature service

Journal Article Tan, L. ; Katoh, Y. ; Tavassoli, A. -A. F. ; ... - Journal of Nuclear Materials

Reduced-activation ferritic-martensitic (RAFM) steels, candidate structural materials for fusion reactors, have achieved technological maturity after about three decades of research and development. The recent status of a few developmental aspects of current RAFM steels, such as aging resistance, plate thickness effects, fracture toughness, and fatigue, is updated in this paper, together with ongoing efforts to develop next-generation RAFM steels for superior high-temperature performance. Additionally, to thermomechanical treatments, including nonstandard heat treatment, alloy chemistry refinements and modifications have demonstrated some improvements in high-temperature performance. Castable nanostructured alloys (CNAs) were developed by significantly increasing the amount of nanoscale MX (M = V/Ta/Ti,more »« less

Development of new generation reduced activation ferritic-martenstic steels for advanced fusion reactors

Journal Article Tan, Lizhen ; Snead, Lance Lewis ; Katoh, Yutai - Journal of Nuclear Materials

International development of reduced activation ferritic-martensitic (RAFM) steels has focused on 9 wt percentage Cr, which primarily contain M₂₃C₆ (M = Cr-rich) and small amounts of MX (M = Ta/V, X = C/N) precipitates, not adequate to maintain strength and creep resistance above ~500 °C. To enable applications at higher temperatures for better thermal efficiency of fusion reactors, computational alloy thermodynamics coupled with strength modeling have been employed to explore a new generation RAFM steels. The new alloys are designed to significantly increase the amount of MX nanoprecipitates, which are manufacturable through standard and scalable industrial steelmaking methods.
