Abstract

The interface shear properties of squeeze cast A356 Al alloys locally reinforced with Saffil(R) short Al2O3 fibres has been assessed using an asymmetric four point bend test (AFPB). The AFPB test was found to be a suitable method for assessing interface strength. Locally reinforced alloys showed modulus and 0.2% shear proof stress improvements over the monolithic alloys, with similar failure strains to completely reinforced alloys, bur reduced shear failure strength. The addition of Fe caused little change in the interface shear properties, but a T6 heat treatment substantially increased 0.2% shear proof stress and shear failure strength.
