A chessboard-like microstructured AZ91 alloy with multi-heterogenous structures was prepared via a combined processing method of high temperature ECAP and short-time aging. The ECAP-aged alloy exhibited superior mechanical properties with ultimate tensile strength of 406 MPa and elongation to failure of 17.9%.
