摘要	The present work aims to investigate the effects of A356 covering plate temperature on interfacial microstructure and mechanical properties of the cast-rolled Mg/Al composite plate. The results indicate that the interfacial transition zone of Mg/Al can be divided into three regions: region I is adjacent to Mg and may form Mg transition region (δ-Mg and Mg17Al12), region II is adjacent to Al and may form Al transition region (α-Al and Al3Mg2), region III is regarded as the diffusion interfacial intermediate region (Mg17Al12, Mg2Si and Al3Mg2). The increasing temperature of the A356 covering plate results in a continuous rise of the width of the interfacial transition zone, and also the increment of type and volume fraction of the intermetallic compounds. Microhardness in the interfacial transition zone is higher than that of the matrix. It is easy to observe the phenomenon of brittle fracture along the brittle phase during the shear strength test. There occur cleavage fracture and quasi-cleavage fracture, both of which are brittle fracture, at AZ31 side and A356 side, respectively. The shear strength of the composite plate reaches its maximum value of 108 MPa when the temperature of the A356 covering plate is 640. © 2019, Materials Review Magazine. All right reserved.
