Abstract
The present invention relates to the use of positron annihilation spectroscopy (PAS) as a method for the measurement of material damage in hot gas path components in industrial gas turbines. A method measuring material damage, expended life and remaining life, using PAS, in nickel and cobalt based superalloy turbine components where the damage has been created by engine operational exposure, is provided. The method can also be used to assess damage to metal components in steam turbines, heat exchangers and generators, as well as damage to other metal, ceramic, plastic and composite articles.
