Effect of Process Parameters on Microporosity and Nanomechanical Properties of Aluminium Cenosphere Composite Foam Developed by Spray Forming Route

Abstract

The present work aims at understanding the effect of process parameters on the porosity and forming route. A detailed investigation of the microporosity and nano have been undertaken through microcomputer tomography (µ respectively. The µ maximum of CF have been by nanoindentation analysis and compared with commercially pure (CP) aluminium. The sphericity results of the foam show that the pores are near spherical (with a sph diameter is below 50 µm, beyond which, the sphericity index decreases (0.175 to 0.4). The results of nanoindentation (for CP aluminium) to 673±54 MPa and energy absorption from 86±10 however; it decreases the elastic modulus from 58±3 (for CP
