Full TextAbstract
Aluminum foam is a group of advanced materials with interesting properties such as: light weight, high energy absorption and recyclability. In this study, Calcium Carbonate as a foaming agent in quantities of 10 and 15 wt. % was added to Al- 5wt. % Al2O3 Nano composite powder mixture. In order to produce foams from foamable precursors, foaming temperatures varied from 950 °C to 1050 °C according to the decomposition temperature of CaCO3. The results revealed that maximum compressive strength and yield stress of Al-Alumina Nano composite foam was higher than Al non reinforced foam. Moreover, the influence of Al2O3 Nano particles on structure of pores was investigated by analyzing the microscopic images of the foams.
