FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to production of refractory highly porous permeable cellular alloys. It can be used for production of filters, noise absorbers, catalyst carriers, heat exchange systems and structural materials operated under high temperatures in power production, machine building, chemical industry, etc. Suspension of the mix of powders is prepared and applied on porous polymer material. Organic substances are removed and workpiece is sintered. Thereafter said workpiece is subjected to force effects in the range of material elasticity to strain the workpiece till material fluidity. Now, said force effects are relieved.
EFFECT: higher strength, longer life.
