On the non-classical crystallographic slip in Tin+1AlCn MAX phases

In this work, we investigate the effect of atomic stacking on non-classical (non-Schmid) crystallographic slip in a class atomically layered ternary carbides referred to as MAX phases with general formula Mn+1AXn, where value n represents sequence. To end, have carried out compression tests single crystal micropillars Ti3AlC2 range orientations and compared results that Ti2AlC. Our show similar Ti2AlC, also exhibits slip, wherein depends both resolved shear stress normal plane. However, for intrinsic critical is greater than while frictional resistance smaller The implications these findings macroscopic response polycrystalline aggregates two discussed.
