镁基复合材料及其制备工艺研究现状与展望OA北大核心CSTPCD

Magnesium and magnesium alloys are the lightest metal structural materials,but the shortcomings in strength,wear resistance and high temperature resistance have limited their wide application in engineering field.Magnesium matrix composites are one of the most important ways to improve the mechanical properties of magnesium alloys and achieve industrialization,which can overcome the above disadvantages with the advantages of magnesium alloys.Therefore,theoretical and experimental studies on magnesium alloys and their composites are of great importance.In this paper,the common reinforcing phases in the preparation of magnesium matrix composites are classified according to their forms,and their corresponding strengthening mechanisms are described,while the current status of magnesium matrix composites research is introduced with the preparation process and simulation studies,and the development trend and research direction of magnesium matrix composites are prospected.
