Abstract

The development of new aviation products requires the improvement of applicable alloys. Alloying complication of disk Ni-base superalloys leads to technical difficulties in their production and particularly during forging. Powder metallurgy allows successfully solving this problem and achieving mechanical characteristic that are very difficult to provide with traditional production methods. This article presents the basic principles of Russian P/M disk alloys development and also points the perspective directions of research in FSUE «VIAM». The work is executed within implementation of the complex scientific direction 10.2. «Isothermal deformation on air of new generation heterophase difficult-to-form superalloys» («The strategic directions of development of materials and technologies of their processing for the period till 2030») [1].
