Performance Enhancing of Spray Formed Al/Graphite Alloy Composite by Rolling
Surendra Kumar Chourasiya,Gaurav Gautam,Devendra Singh 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.6
The present study outlines the effect of warm rolling on the Al/Graphite alloy composite to investigate its effect on mechanicalperformance. The Al/Graphite alloy composite has been fabricated by the spray forming process and has been subjectedto the rolling at 250 °C with varying reduction. The rolled composite has been studied under different characterizationtechniques such as X-ray fluorescence (XRF), optical microscopy, scanning electron microscopy with energy dispersivespectroscopy (EDS) and tensile tester. The XRF and EDS results indicate that the Al/Graphite alloy composite is successfullyformed. The microscopy results show that the grain size of α-aluminium and agglomeration of the particles refine byrolling and they continuously decrease with an increase in rolling reduction. The strength and percentage elongation of thecomposite improves by rolling and they continuously increase with an increase in rolling reduction. Further, the fracturesurface study has also been performed and it indicates that the fracture of the composite alters from brittle to ductile modewith an increase in rolling reduction. The appeared fracture surface of the composite has also been correlated with the producedmicrostructure and the tensile properties.
