Effect of Multiaxiality on the Stress Rupture Properties of P92 Steel

open access: yesIranian Journal of Materials Science and Engineering
High thermal conductivity, low coefficient of thermal expansion makes P92 a candidate material for Ultra Super Critical (USC) power plant piping. Microstructural features viz., high dislocation density, lath martensitic microstructure, fine precipitates of M23C6 and MX (X=C, N) contribute towards the high rupture strength.
