Abstract
To produce aluminum foams with complicated shape, an additive process of aluminum foam is proposed. Experiments of producing aluminum foam by extruding and foaming of precursor from heated die are conduced to deposit aluminum foam on a stage for the additive process. The precursor is made by hot powder extrusion of A6061 and TiH_2. The speed and the die temperature in the extruding and foaming of precursor are examined. The experimental results show the density distribution within the aluminum foam.
