Fabrication of in-situ Al2O3 - TiCp/Al composites by melting and casting technique

摘要

In situ Al2O3 and TiC particles reinforced aluminium matrix composites were successfully fabricated using melting and casting technique.The microstructures and thermal behavior of samples were studied by means of X-ray diffractometer(XRD),scanning electron microscopy(SEM),and differential scanning calorimetry(DSC).The results indicated that fined Al2O3 and TiC submicron particles were in situ formed,and the apt temperature was beneficial to eliminate large intermetllic Al3Ti plates.
