| Abstract Scope |
In this research, powder metallurgy was employed to synthesise a light-weight, high-strength hybrid reinforced AMCs with graded properties. The investigation focuses on the influence of CNT, Y2O3, and SiC reinforcements on various aspects including structure, morphology, phases, thermal stability, and mechanical properties. Continuous variation of CNT (0-2.5wt.%) were done simultaneously to prepare a BULK graded structure. Mechanical and micro structural characterizations were carried out with the aid of SEM-EDS, instrumented indentations to establish structure property co-relation. Further characterization of the composite materials was conducted using X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), indentation techniques and dynamic mechanical analyser (DMA). We found that milling provides uniform distribution of reinforcements and XRD analysis revealed the formation of minimum reaction products. SEM results supports the intactness of interlayers in the bulk samples. Thermal properties characterized through TMA shows 50% reduced coefficient of thermal expansion for the bulk composites. |
