Stabilization of the Titanium Vibration Damping Wires in the Steam Turbine Blades System

Damping wires are usually used for damping of vibration blades in the steam turbines. Chromium steels or titanium alloys are still applied materials for producing the vibration damping wires. In this paper the stabilization method of the titanium vibration damping wires in the steam turbine blades system is performed. Microstructure and mechanical properties of the damping wires made of WT3-1 titanium alloy after cold and hot bending processes were presented. Analysis of the investigation results cold and hot bended vibration damping wires suggest, that stabilizing by hot bending of the titanium wires in the steam turbine blades system can be used in practice with successful.
