摘要

Abstract

BSTRACTThe first Fe-based MAX phase is realized by solid-state substitution reaction of an Fe/Au/Mo

GaC thin-film diffusion couple

as determined by X-ray diffraction and scanning transmission electron microscopy. Chemical analysis together with elemental mapping reveals that as much as 50 at.% Fe on the

site can be obtained by thermally induced Au and Fe substitution for Ga atomic layers in Mo

GaC. One-sixth of the original Ga is also replaced by Au atoms. When annealing Mo

GaC thin films covered with Fe only

the Mo

GaC phase remains intact

that is

Au acts as a catalyst for the substitution reaction.

IMPACT STATEMENT

The first direct evidence showing Fe-containing MAX phase

with Fe ∼50 at.% on the

sites is presented

synthesized by thermally induced Fe and Au substitution reaction catalyzed by Au.
