FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular to the production of highly porous foam metals. It can be used, when manufacturing ultralight construction products and sandwich panels, and as damping elements in systems of passive protection from dynamical loads. Carbamide granules are mixed with a liquid binder in the form of polyurethane water-dispersion varnish in the amount of 1.2-1.8% of the weight of carbamide granules. In the resulting mixture, metal powder is added, mixed to obtain composite granules, pressed and dried. Then, carbamide is removed by dissolution, and the mixture is sintered.
EFFECT: producing defect-free highly porous material, including of hardly deformable powders, including such as spherical powders of Ti6A14V alloy or nickel superalloys.
