| Abstract Scope |
In this study, we employed powder metallurgy techniques along with ML to fabricate a light-weight, high-strength hybrid reinforced aluminum metal matrix composite with 1-D graded properties. The investigation focuses on the influence of CNT, Y2O3, SiC reinforcements on structure, morphology, phase composition, thermal stability, and mechanical properties. Continuous variation of CNT and Y2O3 (0-2.5wt.%) were done for a graded structure upon consolidation. Mechanical and micro-structural characterizations were carried out with the aid of SEM-EDS, instrumented indentations to establish structure property co-relation. Further characterizations were conducted using X-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy (SEM), indentation techniques and DMA. We found that milling resulted in the 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 DMA shows 50% reduced coefficient of thermal expansion for the bulk FG composites. |
