Paper Title:
Effect of Squeeze Pressure on Microstructure, Aging and Mechanical Properties of A357/ ZrO2 Composite
  Abstract

AlSiMg (A357) composites containing 10 vol. % zirconia (ZrO2) particulates have been synthesized by the stir process followed by squeeze casting. Pressures of 25 and 50 MPa were maintained during solidification in specially designed die and ram and maintained at 250°C. Results show that with increasing squeeze pressure, the density increases while porosity decreases. The hardness of squeeze cast composite is higher than that of stir casting by about 10%. The compression properties have been evaluated and compared. The results show that compressive strength increases with squeeze pressure.
