https://doi.org/10.22349/1994-6716-2018-95-3-48-56
Abstract
The way to set ageing regimes of P/M Ni-base superalloy for disk application was demonstrated. The optimal ageing temperatures were identified by microstructure investigations. Mechanical tests of the material with different volume ratio of carbide phases were carried out. The obtained results confirm the correctness of the detected patterns.
Supporting agencies: The present investigation carried out in the framework of the “Strategic directions of development of materials and technologies for the period up to 2030” has been done according to clause 10.2 “Isometric deformation of heterophase hardly deformable heat-resistant new generation on air”
