Microstructures and mechanical properties of 5 wt. percent Al_2Y_p/Mg-Li composite

摘要

A new Mg-Li matrix composite with 5 wt. percent Al_2Yparticulates was developed by stir-casting technique, its microstructures and properties were investigated systematically. The results show that, the A1_2Y intermetallics particles distribute in Mg-Li matrix homogeneously, and a good Al_2Y_p/ Mg-Li interface is developed wherein there are no reaction products or obvious elements diffusing. The composite has a higher tensile strength compared with matrix alloy, whose good ductility is kept. fi 2005 Elsevier B.V. All rights reserved.
