Effect of brazing on the creep and low cycle fatigue properties of a single crystal superalloy

Innogy plc has evaluated the effect of brazing on the microstructure and creep strength of the single crystal superalloy CMSX-4, used in industrial gas turbine blades and has also evaluated the low cycle fatigue properties of brazed joints in the alloy.

A mechanistic understanding of the mechanism of microstructure degeneration and restoration during brazing has been gained and the limits on restoration of the low cycle fatigue strength by brazing have been determined.

Innogy is a power generator and supplier of O&M services and will use these results to support its activities in the field of gas turbine refurbishment. The know-how will also enable Innogy to participate in future related R&D programmes.
