Ni superalloys are used for high T applications that require good mechanical properties. The aim of reaching higher service T forces the development of new materials. VDM alloy 780 Premium has been developed for higher service T and this work shows its in-situ structural characterization by means of XRD and ND. The morphology is studied by SEM and SANS, the solvus T of the different phases is determined and the structural properties correlated with hardening of the materials.
