Synthesis and mechanical properties of high-purity Cr2AlC ceramic

▶ New processes for the synthesis of dense and high-purity Cr2AlC are presented. ▶ Delamination, kink bands, monolamellar kink and transgranular crack are observed. ▶ Mechanical properties of the high-purity and dense Cr2AlC are determined. ▶ Effect of impurity on the mechanical properties of Cr2AlC has been investigated.
