Nanoindentation into a dual-phase bicontinuous lamellar high-entropy alloy
Journal of Materials Research and TechnologyThe plastic response of a dual-phase high-entropy alloy to nanoindentation is studied using molecular dynamics simulation. The sample has a bicontinuous lamellar structure consisting of an equiatomic FeNiCrCo fcc phase and an Al50(FeNiCrCo)50 bcc/B2 ...

Synthesis and Self-Assembly of fcc Phase FePt Nanorods
Journal of the American Chemical Society, 2007 We report a synthesis of FePt nanorods by confining decomposition of Fe(CO)5 and reduction of Pt(caca)2 in surfactant reverse cylindrical micelles. The controlled nucleation and growth kinetics in confined environment allows easy control over Fe/Pt composition, nanorod uniformity, and nanorod aspect ratio.
