Paper Abstract

The objective of the present investigation was to evaluate the mechanical properties of Al/ZrO2 composite prepared via vortex or direct incorporation method. An Al-356 alloy and ZrO2 particles with average size of 1 micron as the reinforcing material were used as the raw materials. The results showed that addition of ZrO2 particles to the matrix increases significantly the mechanical properties of aluminum. The UTS of a sample having 15 vol. percent ZrO2 prepared in 750°C, increased from 145 to 232 MPa and the hardness of the sample increased from 45 to 64 Brinel. The Al-356/ZrO2 composite specimens fail in a macroscopically brittle manner with little or no necking observed around the fracture site and with a relatively flat fracture surface.
