Abstract

The article presents the mechanical properties of VT6 alloy disk forgings manufactured under various production conditions with different heat treatment modes. The research results presented in the main part of the article were obtained in the initial period of work on the introduction of VT6 alloy for engine parts and were confirmed later during the certification of disk forging weighing up to 100 kg. A comparison of the mechanical properties of stampings of the same type made of VT6 and VT3-1 alloys is given. The discussion pays special attention to the factors leading to a decrease in the viscosity characteristics of the material.
