Effect of Zircon Silicate Reinforcements on the Microstructure and Properties of as Cast Al-4.5Cu Matrix Particulate Composites Synthesized via Squeeze Cast Route

The as-cast microstructure and properties of Al-4.5Cu/ZrSiO4 particulate composite synthesized via squeezed casting route was studied, varying the percentage ZrSiO4 in the range of 5-25wt%. The result obtained revealed that addition of ZrSiO4 reinforcements, increased the hardness value and apparent...
