The end results shows mechanical properties and microstructure behavior of composite was improved compared to the monolithic alloy. Microstructures of the composites in as cast conditions shows uniform distribution of the particles and reveals the better bending in case of zircon reinforced composites compared to the TiB2 composites. But increase in the amount of reinforcement shows better conditions in case of TiB2 reinforced composites.
