Abstract
Large turbomachines such as steam turbines and gas turbines will have an operational lifetime which may be measured in terms of decades. During the operational lifetimes it is desirable to monitor the condition of major parts of the turbomachine such as rotors and rotor wheels. Procedures are available for non-destructive testing of major turbomachine parts but it is desirable to affirm the actual condition of a turbomachine rotor by a sacrificial test of a speciment taken from a forging from which the actual turbomachine part was made. Further, it is desirable that the specimen be in service with the turbomachine part so as to obtain an accurate operating experience. To this end, a specimen taken from a turbomachine forging is affixed to a finished turbomachine part and then run with the machine for latter removal and test.
