【 摘 要 】

Particulate Nano Aluminum Hybrid Composites (PNAHC) are prepared by the combined effect of stir casting with ultrasonic process. PNAHC is prepared by reinforcing 3% by weight of rice husk char (RHC) and with varying weight percentages of TiC such as: 3%, 6%, 9% and 12%. The effect of the reinforcements on the PNAHC is studied by tensile, compressive, bending, impact, microhardness and density. Halpin-Tsai and the rule of mixing equations serve to measure the elastic modulus and the Poisson ratio. The formation of Al12Mg17 as an intermediate element and other key elements such as Aluminium, TiC and SiO2 are consistent with the XRD technique. The homogeneous dispersal of the reinforcements is verified using the SEM model with EDS. Microstructural arrangements of the reinforcements and its behavior on test load conditions under casting process with and without ultrasonic-assisted stir casting where compared and reported.
