FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly to production of composite materials based on Nb intermetallic compound. It can be used in fabrication of parts intended for long operation at high thermal and mechanical loads, for example gas turbine engine high-temperature parts: working and nozzle vanes, fire tubes elements and other components operated at temperatures approximating to 1600°C. Initial powder mix is subjected to mechanical doping in protective atmosphere for 40-50 hours. Then hot isostatic doping is performed at 1450-1550°C and pressure of 25-35 MPa for not over 5 minutes.
EFFECT: uniform structure, high relative density at high yield of suitable material, maximum efficiency.
