摘要

Abstract

BSTRACTNew MAX phases Ti

(Al

1−

)N and Nb

CuC were synthesized by A-site replacement by reacting Ti

AlN and Nb

AlC

respectively

with CuCl

or CuI molten salt. X-ray diffraction

scanning electron microscopy

and atomically resolved scanning transmission electron microscopy showed complete A-site replacement in Nb

AlC

which lead to the formation of Nb

CuC. However

the replacement of Al in Ti

AlN phase was only close to complete at Ti

(Al

0.1

0.9

)N. Density-functional theory calculations corroborated the structural stability of Nb

CuC and Ti

CuN phases. Moreover

the calculated cleavage energy in these Cu-containing MAX phases are weaker than in their Al-containing counterparts.
