Influence of 236 hours Engine Rig Test on Structures and Properties of First Stage Turbine Blade of GH220 Alloy

    Graphical Abstract
    • Abstract
  • The changes of surface coating, basic structures and mechanical proper-tie? in first stage turbine blade of GH220 alloy tested by engine rig for 236 hour? has been investigated. The results show that the structures of alloy are stable and properties of alloy still good. The isothermal treatment process at 1070℃ is suitable. It is shown that this alloy （blades） has greater potentiality.
