摘要

The thermal stability of YAL₂p/MgLiAl composites was studied by XRD, TEM, HREM and material tensile teat. The results show that, there are no detectable products on the interface after fabrication or subsequent heat treatment, and the interface between YAl₂ and MgLiAl alloy is not weakened after the heat treatment. The tensile strength and elongation of the composite after being solution treated at 350°C for 10 h exceed those of the as-cast composite 11% and 20%, respectively. The Gibbs free energy was calculated to assess the thermodynamics driving force for the reaction of YAL₂ and MgLiAl matrix.
