TLDR
In this article, four ferritic alloys based on the composition Fe-14Cr-3W-0.4Ti were developed with a predominant dispersion of either oxide particles or nano-size Y-, Ti-, O-rich clusters, or nanoclusters (NC).About:

Structural materials for fission & fusion energy
Steven J. Zinkle,Jeremy T Busby +1 more
TL;DR: In this article, a strategy for designing high-performance radiation-resistant materials is based on the introduction of a high, uniform density of nanoscale particles that simultaneously provide good high temperature strength and neutron radiation damage resistance.

Atomic structure of nanoclusters in oxide-dispersion-strengthened steels
TL;DR: This study provides compelling evidence that the nanoclusters have a defective NaCl structure with a high lattice coherency with the bcc steel matrix, which seems to be the most important reasons for the unusual stability of the clusters at high temperatures and in intensive neutron irradiation fields.

Irradiation-tolerant nanostructured ferritic alloys: Transforming helium from a liability to an asset
G.R. Odette,David T. Hoelzer +1 more
TL;DR: Nanostructured ferritic alloys (NFAs) have the potential to make transformational contributions to developing advanced sources of fission and fusion energy as discussed by the authors, which can transform helium from a liability to an asset by forming a high density of nm-scale bubbles that act as sinks for point defects.
