of their resistance to stress rupture at high temperature in certain embodiments the plate 26 comprises a material that may withstand even higher temperatures without oxidizing ren u00e9 142 u2122 and haynes 214 u2122 haynes international alloys are exemplary materials for the plate 26 because of their resistance to oxidation however many other materials may be used for the plate 26 including but not limited to ren u00e9 195 u2122 general electric company and haynes 230 u2122 haynes international alloys although the present embodiment illustrates the use of two plates plates 24 and 26 it should be noted that any number of plates may be used for example in some embodiments a single plate being both resistant to low cycle fatigue and oxidation may be used alternatively a plurality of plates may be stacked to produce a gradient effect with each plate possessing the optimal properties for the thermodynamic and mechanical stresses at the particular location on the airfoil for example an intermediate plate comprising a material having an intermediate level of creep resistance and oxidation resistance relative to the plates 24 and 26 may be added between the plates 24 and 26 the expression u201c different material u201d and variations thereof as used herein encompasses the use of different alloys among different components the term also encompasses the use of the same alloy in different orientations among different components where the difference in orientation appreciably affects the manner in which the component responds to thermodynamic and mechanical stresses at the particular location where the component is placed on the turbine blade unlike.
