| description | The study presents the comparative analysis of the compressive response for the experimental aluminium foams of different parent alloys fabricated by melt processing with/without Ca additive and an expensive conventional TiH<sub>2</sub> foaming agent or a cheap alternative CaCO<sub>3</sub>. It was recognized that the response of the foams is significantly dependent on the type of foaming agent and Ca additive due to the formation of low ductile and brittle products created in the foaming process. The presence of deformation bands and brittle eutectics in material, Al<sub>3</sub>Ti particles/layers, partially decomposed TiH<sub>2</sub>, Ca containing compounds, etc. cause a reduction of the foam’s compressive strength and deviation of its mechanical profile from the theoretical predictions. In addition, the usage of an inexpensive CaCO<sub>3</sub> foaming agent offers numerous indisputable advantages compared to TiH<sub>2</sub>, resulting, particularly, in enhancing the energy absorption ability of foams. |
