Abstract

•Open-cell IN625 foams with variable porosity and pore size were produced by a newly developed template replication method.•There was a linear correlation between the average pore size of the polymeric templates and the produced IN625 foams.•It indicates the advantage of microstructure controllability of the template replication method.•Sound absorption coefficient of IN625 foams was predicted using measureable microstructure parameters via FP and DB models.•IN625 foam with α>0.9 at f>1500 Hz of 50 mm thickness has been successfully fabricated and accurately predicted.
