Features of a nano-twist phase in the nanolayered Ti3AlC2 MAX phase

Abstract : Complex intermetallic materials known as MAX phases exhibit exceptional properties from both metals and ceramics, largely thanks to their nanolayered structure. With high-resolution electronic microscopy supported by atomistic modelling, we reveal in this work the formation of a nano-twist phase in the nanolayered Ti3AlC2. We evidence basal pure-twist symmetric boundaries that can be represented by either a screw dislocations networks or pair of disclinations loop.
