The Mechanical Performance of Aluminum Foam Fabricated by Melt Processing with Different Foaming Agents: A Comparative Analysis

The study presents the comparative analysis of compressive response for experimental aluminium foams different parent alloys fabricated by melt processing with/without Ca additive and an expensive conventional TiH2 foaming agent or a cheap alternative CaCO3. It was recognized that is significantly dependent on type due to formation low ductile brittle products created in process. presence deformation bands eutectics material, Al3Ti particles/layers, partially decomposed TiH2, containing compounds, etc. cause reduction foam’s strength deviation its mechanical profile from theoretical predictions. In addition, usage inexpensive CaCO3 offers numerous indisputable advantages compared resulting, particularly, enhancing energy absorption ability foams.
