Abstract
The AlNp/2024 composite with a high volume fraction (50%) was fabricated by squeeze casting. Its mechanical properties were investigated by tensile te sts at ambient temperature and the microstructure was observed by a transmi ssion electron microscope (TEM). It was indicated that after six thermal co oling cycles treatment the AlN/2024AI composite exhibited higher elastic li mit (sigma (0.01)), tensile strength (UTS) and elastic modulus (E). TEM obs ervation showed that there was higher dislocation density both in the matri x and the particle. delta' phase is the mainly precipitate.
