FIELD: metallurgical engineering.
SUBSTANCE: method includes hydrogenation of powders, sintering in vacuum and cooling to room temperature. Hydrogenation of the powder is carried out in demountable or integral forms of steel or glass, corresponding to the shape of the article, at a temperature of 600-800 °C to a hydrogen concentration of 0.1-1% by weight, followed by vacuum annealing of the article at a temperature of 600-800 °C for 30-120 minutes, destroy or disassemble the moulds and sinter the resulting prepared semifinished product in a vacuum oven at a temperature of 900-1200 °C for 30-120 minutes.
EFFECT: production of porous products without using heat-resistant high-temperature moulds for sintering is provided.
