Studies on Microstructure and Mechanical properties of Aluminium Foam prepared by Spray Forming Route

Abstract

In the present study, attempts have been made to develop aluminium foam using cenosphere as a space holder by spray forming route. The main process variables were, applied current, gas pressure, and weight fraction of space holders. Detailed investigation of the effect of process parameters on the microstructures were undertaken to optimize the processing zone for the development of foam. The mechanical properties in terms of micro hardness, compressive strength, and tensile strength have been evaluated in details. Finally, the deformation behaviour of the aluminium foam has been established.
