Abstract

A method (200) and system for determining creep capability of turbine components (120) is provided. A plurality of turbine components (120) are manufactured from a material having known creep characteristics. Each of the plurality of turbine components (120) is subjected to at least one of tensile stress, centrifugal stress and thermal stress, until a measureable amount of creep is acquired. The turbine components (120) so tested are compared against known creep characteristics for the material used in the components. Components exhibiting an amount of creep greater than a predefined amount of creep will be separated from the plurality of turbine components (120) and not placed into service.
