Abstract
The zinc foam was studied in the porosity range of 78-91 %. It was found that to foam zinc it is necessary to overheat significantly the foam above the melting temperature of metal or to use higher amount of foaming agent. Deformation behaviour of zinc foams is comparable to aluminium foams behaviour: compression strength of zinc foams is significantly lower at similar density; foams of equal porosity possess almost identical compression strength. Situation is similar when absorbed deformation energy is considered. Thanks to low foaming temperature, zinc foams can be used for partial stiffening of complex hollow profiles by “in-situ” foaming.
