What is Influence of matrix strength on reinforcement fracture and ductility in AlAl2O3 composites about?
Two AI alloys (2014 and 6061) reinforced with 15 vol.% A1203 particulates were tested in the naturally aged and peak-aged conditions to study the influence of matrix strength on the mechanisms controlling the tensile ductility of these composites. Periodic measurements of the degradation of elastic properties during deformation, as well as quantitative metallography, indicated that the dominant failure mechanism was progressive fracture of the particulates during deformation. The probability of particulate fracture increased with the reinforcement size, and elongated particulates oriented in the loading direction were more prone to fail than small, equiaxed ones. It was also observed that the particulate fracture rate increased with the matrix strength and that the naturally aged composites were able to withstand more damage prior to failure than those artificially aged at high temperature. When a critical volume fraction of broken reinforcements was reached at a given section of the specimen, matrix failure led to specimen fracture by a ductile mechanism of shear failure or void nucleation and growth from inclusions or precipitates in the matrix.
