Abstract: According to one aspect, a rotor structure and method of assembling a rotor structure for rotating machinery include a first rotor portion assembled on a tie bolt in abutment with a stop surface and a fastener assembled on the tie bolt at a second axial location spaced from the first axial location to capture the first rotor portion on the tie bolt between the first and second axial locations. A second rotor portion is secured on the tie bolt in abutment with a second stop surface spaced from the first stop surface.

Abstract: An article that includes a polymer-based substrate; and a metallic nano-crystalline coating on at least a portion of the polymer-based substrate, where the metallic nano-crystalline coating defines an average grain size less than about 20 nanometers, where the portion of the polymer-based substrate has a first Young's modulus and the metallic nano-crystalline coating has a second Young's modulus, where the first Young's modulus is at least five times less than the second Young's modulus.
