摘要

Abstract

BSTRACTWe use analytical aberration-corrected high-resolution scanning transmission electron microscopy to image the atomic structure of the layered ternary transition metal (M) borides

AlB

and MoAlB. In these ternaries

MB layers and Al single or double atomic layers are interleaved. The atomic positions of the M elements and Al are clearly resolved by Z-contrast images. The following structural defects are also found and described herein: a 90° twist boundary along [010

]

in Cr

AlB

a tilt boundary in Fe

AlB

and Mo

AlB

-like stacking faults in MoAlB

where some of the MB-based structures are intercalated by one (instead of two) Al layer(s).
