Vibration was adopted to enhance the interface bonding of Mg–Al bimetal prepared by lost foam compound casting (LFCC) technique. The bimetallic composed three layers: layer I (Al3Mg2 and Mg2Si phases), II (Al12Mg17 III + δ-Mg eutectic structure). With increase in vibration acceleration, cooling rate increased, resulting decrease reaction duration that generates intermetallic compounds (IMCs) (i...
