Abstract
Hot rolling was carried out on the extruded 6061 Al alloy composite reinforced with 10%(Al₂O₃)p along a direction perpendicular to the extrusion direction of the composite. The variations of the Young`s modulus as a function of the rolling ratio were measured along the longitudinal and the transverse directions using the standard sonic resonance test method. The results showed that the Young`s modulus increases with increasing rolling ratio. Qualitative analyses were made on the observed experimental results based on the microstructural changes induced by the rolling and annealing operation.
