  • System and method for full-scale sampling to conduct material tests on a steam turbine rotor
    Patent number: 11592362
    Abstract: A method for generating material test samples for conducting material tests of a legacy steam turbine rotor having an inter-blade region rotor surface, and an inlet region rotor surface adjoining the inter-blade region rotor surface. The method includes forming an annular ring of rotor material in the sample area and forming a material test sample from a portion of the annular ring. Also described is a legacy steam turbine rotor including an inter-blade region rotor surface, and an inlet region rotor surface adjoining the inter-blade region rotor surface. The steam turbine rotor having a groove formed therein, and wherein the groove is machined to enable removal of material from the steam turbine rotor to form samples configured to enable at least one of conducting material property tests and operating the improved legacy steam turbine rotor at an expanded thermal stress compared to the legacy steam turbine rotor.
