Thermodynamics and Interfacial Structure of TiAlp/Mg-Li-Al Matrix Composites

摘要：

　　A new MgLiAl matrix composite with 10wt%TiAl particulates was developed by stir-casting, and its microstructures, properties and chemical compatibility were investigated systematically by XRD, TEM, HREM and material tensile teat.The results show that, there is a good connection between the Mg-Li matrix and TiAl particulates.There are no detectable chemic products on the interface after fabrication or subsequent heat treatment, and the interface between TiAl and MgLiAl alloy is not weakened after the heat treatment, and the thermodynamic potential for the reaction between the matrix and TiAl particulate is very low, the composite system is stability during fabrication or subsequent heat treatment.The composite has an improved tensile strength compared with matrix alloy, while a good ductility is kept.
