    Effect of reinforcement concentration on the properties of hot extruded Al-Al2O3 composites synthesized through microwave sintering process حسب Reddya, M. Penchal

    منشور في 2017
    "…Results showed that, as the content of hard ceramic particles increases, it improves overall mechanical properties including microhardness, 0.2% yield strength, ultimate compression/tensile strength, and Young's modulus while the ductility and co-efficient of thermal expansion decreases. XRD patterns and SEM/EDS mapping images show a uniform distribution of Al2O3 particles in the Al matrix. …"
