1. A shroud hanger assembly for dimensionally incompatible components, comprising:
a multi-piece shroud hanger formed of a first material, said multi-piece shroud hanger having a forward hanger portion and a rearward hanger portion defining a cavity therebetween, the multi-piece shroud hanger further comprising a linearly extending chordal interface rib on at least one of said forward hanger portion or said rearward hanger portion for engagement with the other of said forward hanger portion and said rearward hanger portion; and
a shroud formed of a low coefficient of thermal expansion second material, said shroud disposed between said forward hanger portion and said rearward hanger portion, wherein the shroud has a first axial length, and wherein prior to the shroud being disposed between said forward hanger portion and said rearward hanger portion the cavity has a second axial length, wherein the first axial length is larger than the second axial length to force a cantilever bending of at least one of the forward hanger portion or the rearward hanger portion away from the cavity when the shroud is disposed between said forward hanger portion and said rearward hanger portion such that at least one of said forward hanger portion or said rearward hanger portion are configured to apply an axial interference force on said shroud.
