The status of nanostructured ferritic alloys (NFAs) is summarized. The science underlying
NFAs has emerged as a remarkably comprehensive and high quality body of research. The …

Tungsten is generally too brittle to serve a robust structural function. Here, we explore the
fracture toughness of 90–97 wt% W Ni-Fe liquid phase sintered tungsten heavy alloys …

In this study, the pre-alloyed powder Fe-22Cr-5.1 Al-0.5 Ti-0.26 Y (wt%) was prepared by
nitrogen atomization and characterized with the aid of focused ion beam (FIB) and …

Abstract Fe-Cr-Al alloys, owing to their absence of allotropic transformation, require multiple
cycles of rolling and recrystallization annealing processes to achieve substantial grain …

Nanostructured ferritic alloys (NFAs) contain an ultra-high density of 2–4 nm fcc pyrochlore Y
2 Ti 2 O 7 nano-oxides (NOs) embedded in a bcc Fe-14Cr ferritic matrix. Characterization of …

The high-strength low-alloy steel plates with varying Ni/Mo contents were manufactured
using the thermos-mechanical control process. The investigation was conducted to explore …

Tempered medium carbon steel with poor low-temperature toughness always limits its
practical applications, while temper forming process can realize the strengthening …

Cr-stabilized nanostructured ferritic alloys (NFAs), dispersion strengthened by an ultra-high
density of nanooxides, are attractive candidates for many nuclear energy applications due to …

The fracture properties and susceptibility to crack-divider delamination (or splitting) of three
commercially produced high-toughness X70 pipeline steels are evaluated with Charpy …

Y-containing CLAM steels were melted via vacuum induction melting and electroslag
remelting. In this study, the evolution, microstructure, and mechanical properties of the alloy …
