In the development of new high-temperature alloys for gas turbine applications, various candidates are under consideration. CoRe based alloys strengthened by carbides, eventually by Cr2Re3 type σ phase is one promising option. However, the high temperature microstructure and its stability is of great importance for the application. High-temperature cycling experiments performed in-situ on CoRe-1 alloy in parallel with neutron diffraction measurements (Stress-Spec and SPODI) indicate, how heating, cooling and hcp-fcc phase transformation of the Co-matrix influence the stability of the minority phases during repeated thermal cycles.
