Description
Summary:The differences between the chemical compositions, the technologies of melting and remelting, and the heat-treatment conditions of the granulated and deformed nickel superalloys used for the production of GTE disks are considered. The efficiency of using a metal is analyzed for the disk blank fabricated by HIP and is compared with isothermal deformation. The quality control methods applied in the modern Russian practice are compared.
