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.
