Abstract Scope |
In this study, we employed powder metallurgy technique to fabricate a light-weight, hybrid reinforced Al metal matrix layered composite with 1-D graded properties. The investigation focuses on the influence of CNT,Y2O3 and SiC reinforcements on various aspects including structure, morphology, phase composition, thermal stability, and mechanical properties.
Continuous variation of CNT and Y2O3 (0-2.5 wt%) were done simultaneously to prepare 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 characterization of the composite materials was conducted using XRD, TEM, SEM and dynamic mechanical analyzer (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. |
