摘要

Abstract

BSTRACTTheoretical investigations on electronic structure

chemical bonding and mechanical properties reveal that MAB phases (CrB

)

CrAl (

= 1–3) exhibit anisotropic electrical and elastic properties

low shear deformation resistance and damage tolerance similar to MAX phases. The main contribution to the electrical conductivity is Cr 3

states and the anisotropic distribution of Cr atoms results in anisotropic conductivity. The high stiffness originates from the strong covalent B–B bonds

while the low shear deformation resistance is underpinned by metallic B–Cr bonds adjacent to Al layer. The possible slip systems are (100)[010
