METHOD OF PRODUCING POROUS MATERIAL BASED ON TITANIUM NICKELIDE Russian patent published in 2020 - IPC C22C1/08 B22F3/23 C22C19/03 C22C14/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, specifically to the technology of producing porous metal materials, and can be used in medical implantology. Method of producing porous material based on titanium nickelide involves two-step sintering of a mixture containing titanium nickelide powder with intermediate exposure between stages. Initial titanium nickelide powder is sifted into fractions and a fraction with particle size of 100 to 150 mcm is selected for sintering, into the mixture is added from 5 to 7.5 % of titanium powder with particle size from 100 to 150 mcm, wherein in the process of two-stage sintering, the first step is carried out at temperature of 1200 ± 5 °C with holding for 15 ± 5 minutes, and second stage at temperature of 1240 ± 5 °C with holding for 15 ± 5 minutes.

EFFECT: higher porosity of produced material and higher deformation resistance.
