Research Progresses of Cast Mg/Al Composite Process Parameters and Composite Interface
Mg/Al composites are widely used in automotive,aerospace and electronic equipment.Compared with the rolling process for preparing composite plates,the casting method can be used to prepare complex composite components,and has the advantages of low cost and high production efficiency.However,the microstructures of Mg/Al composites prepared by casting process is difficult to control and the interface bonding strength is relatively low,limiting the material performances.The factors affecting the properties of the composite include casting process,interface treatment and diffusion layer structure.At present,composites are strengthened mainly by controlling grain size,interface strengthening and interface reaction.In this paper,the effects of the process parameters on the interface of Mg/Al composites prepared by casting process are reviewed,including diffusion layer thickness,the grain size and so on.Finally,proposed author's opinions in this dierction.
