In this study, we report on the compressive behavior of Ti 3 AlC 2 and Al 0.8 Sn 0.2 C MAX phases at room temperature. We found that these two could be classified as Kinking Nonlinear Elastic (KNE) solids. The cyclic stress–strain loops for are typical hysteretic fully reversible. At failure, both compositions fracture in shear with maximum stresses 545 MPa 839 . Consequently, macroshear τ c , 185 242 respectively. addition to grain size effects, presence a ductile x y intermetallic distributed boundaries plays an important role enhancement ultimate SEM observations reveal exhibit crack deflections, intragranular fractures, kink band formation delaminations, push‐in pull‐out.
