Research Progress of Magnesium Matrix Composites Based on Friction Stir Processing
Magnesium and its alloys have the advantages of low density,high specific strength and easy processing.With the continuous progress of science and technology,the performance requirements of magnesium alloys in aerospace and other fields are getting higher and higher,the development and research of magnesium matrix composites have been paid more and more attention.Friction stir processing(FSP)has become one of the most popular research in the composites preparation due to its unique advantages such as low cost,high efficiency and green energy saving,which has a broad application in aerospace,automobile manufacturing,and so on.Recently,researchers at home and abroad have prepared many magnesium matrix composites with excellent properties through the combination of different types of reinforcement and magnesium alloys via FSP.At present,the main reinforcements consist of particle,fiber,graphene,etc.The research progress of friction stir processing of magnesium matrix composites at home and abroad was reviewed,some important research results about the FSP of magnesium matrix composites and its basic problems were illustrated and analyzed,as well as the effects of processing parameters on microstructure and properties of the composites.The research orientation and prospect of magnesium matrix composites via FSP are further proposed,in order to provide guidance for the research and application of FSP technology in the field of magnesium matrix materials.
