FIELD: metallurgy.
SUBSTANCE: invention relates to receiving of turbine stator casing, particularly turbojet engine of aircraft. Turbine stator casing contains envelope and adjusting brackets, directing nozzles of turbine stage, projecting on internal surface of envelope. Envelope is implemented from powder the first alloy. Adjusting brackets are implemented from the second alloy, more refractory, then the first, and are rigidly connected to envelope by means of diffusion welding during hot isostatic pressing. Casing additionally contains insertions, which pass through adjusting brackets and envelope. Insertions are also rigidly connected to casing by means of diffusion welding and at manufacturing of casing there are fixed brackets at one of parts of mould, inside of which it is formed envelope.
EFFECT: there is described turbine stator casing with refractory brackets, manufactured by method of powder metallurgy.
