Production of closed cell foams from the aluminium chip waste

Aluminium metal foams represent a new generation of materials that are characterized by their lightweight structure and unique properties. This research is based on the production of closed cell foams which are made of aluminium alloy chip waste and TiH2 as a foaming agent. The main task was to investigate the influence of different times and temperatures of foaming as well as a different percentage of TiH2 on mechanical and physical properties of foams. Microhardness, energy absorption, density, and compression properties were observed. Compressive strength and energy absorption are higher with the increase in density, while densification strain is lower. It is also concluded that a longer time and higher temperature of foaming lead to lower density values.
