Analysis of Grain Selection during Directional Solidification of Gas Turbine Blades
— In this paper the evolution of grain structure and the control of crystal orientation in gas turbine blades are presented. The conditions leading to the solidification of columnar grain and single crystal blades are analysed, and techniques for producing columnar grain and single crystal blades in industry are reported.
متن کاملCharacterization and Investigation of Grain Selection in Spiral Grain Selectors during Casting Single-Crystal Turbine Blades
Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...
