Abstract: Provided is a composition of a nickel-based superalloy with Ni-8Cr-10Co-0.6Mo-8Ta-8W-1.25Re-5.7Al-0Ti-0.1Hf-0.25Si-0.008B-0.0210C-0.02Y, by which composition improved TMF properties are achieved.

Abstract: A continuous flow machine has at least one annular guide vane carrier. The guide vane carrier, formed at least by a lower part and an upper part detachably connected to same, has at least three guide vane stages retained on the inner circumference of the at least one guide vane carrier, arranged axially behind one another in the flow direction and each having a plurality of radially extending guide vanes. Each of the guide vanes also has a guide vane blade, a base plate and a top plate, wherein the guide vane blade extends between the base plate and top plate. Via the arrangement of the securing pin in an intermediate space accessible in the assembled state, a partial disassembly of the individual guide vane stages is possible, independent of the remaining guide vane stages. The guide vane stages are conventionally mounted via retaining protrusions on neighbouring guide vane stages.
