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

"…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. …"

Novel electroless deposited corrosion — resistant and anti-bacterial NiP–TiNi nanocomposite coatings حسب Fayyad E.M.

"…The addition of TiNi nanoparticles into the NiP matrix leads to the transformation of the amorphous structure of the as-plated NiP into a semi-crystalline one. The microhardness of the composite coating significantly enhances with increasing the TiNi concentration up to 0.4 g L−1 and further improvement takes place after the heat treatment. …"
