Powder-metallurgical aluminum foams are based on preform materials with well-dispersed particles of a foaming agent inside of them. The blowing agent releases the porosity-producing gas during specific heat treatment while the matrix material is at least in a semi-solid state. Once the foam has reached the desired density, the heat supply has to stop, and the material temperature is brought as quickly as possible to a range below the melting point. The process is usually carried out as an oven process and thus presents a corresponding challenge in thermal management. This circumstance becomes even more important with increasing component size. The present article deals with the qualification of field-assisted sintering for this task to achieve more sustainable and safer process control. The advantages lie in higher efficiency due to the direct heating of foamable material from inside and the protection of the surrounding material through targeted cooling. The latter is primarily a considerable advantage in producing sandwich materials with aluminum foam core and aluminum sheets as outer cover layers and could revolutionize it. This work shows the first results of applying the process both in indirect and direct execution.
