Open the CIPO recordAbstract From the Canadian patent
The invention relates to a process for increasing the lifetime of a refractory composite material piece comprising a metallic matrix and a reinforcing phase consisting in aligned monocrystalline fibers made of a metallic carbide when the piece has suffered a plastic deformation in the direction of said fibers. The invention consists in restoring the initial qualities of the piece by subjecting it to d high temperature inferior, to the melting point of the material more precisely at the, temperature at which the piece resumes its initial length after being cooled at ambient temperature. The invention is particularly applicable to pieces forming turbine blades for aircrafts.
