Mechanical properties of the 9Al_2O_32B_2O_3(w)/6061Al composites could be hardly improved by T6 treatment, owing to cause theremarkable interfacial reaction. An observation under high resolution transmission electronmicroscopy on interfaces shows that the serious chemical reaction occurs and the product isAl_2MgO_4. But no such reaction is found at the interfaces of 9Al_2O_3·2B_2O_3(w)/Al compo-site. EDS analysis on the interfaces shows that above mentioned interfacial reaction may beresulted from the interfacial segregation of Mg atoms in 6061Al matrix during sequeeze cast-ing.
