Journal ArticleDOI
Stabilization of nanocrystalline grain sizes by solute additions
TL;DR: In this paper, a review of the grain growth in nanocrystalline materials with emphasis on the grain size stabilization that can result from solute additions is presented, followed by a summary of alloys where the grain sizes can be maintained at annealing temperatures close to the melting point.
Journal ArticleDOI

TL;DR: In this paper, the relative thermal stability of a number of Fe-based nanocrystalline binary alloys was predicted with considerable accuracy using a modified regular solution model for grain boundary solute segregation.
Journal ArticleDOI
Thermal stability of nanocrystalline nickel with yttrium additions

TL;DR: In this paper, the microstructural changes due to annealing were characterized using x-ray line broadening, microhardness, focused ion beam channeling contrast imaging, and transmission electron microscopy.
