Abstract

The interface characterization of the aluminium alloy reinforced with Al₂O₃ particulates ((Al₂O₃)_p/AI composite) was performed using X-ray diffractometry and energy dispersive X-ray spectroscopy. A layer of MgAl₂O₄ single crystals was observed at the (Al₂O₃)_p/Al interface in the as-received extruded composites. Such MgAl₂O₄ crystals formed at the surface of (Al₂O₃)_p are believed to grow by consuming a certain amount of (Al₂O₃)_p. Upon loading, interfacial debonding was observed to occur at the boundary between MgAl₂O₄ and the aluminium alloy, or along the MgAl₂O₄ layer itself. These experimental observations are correlated with the tensile properties of such composites.
