In the development of new high-temperature alloys for gas turbine applications, a CoRe based alloy strengthened by Cr23C6 type carbide and Cr2Re3 type σ phase precipitations is under consideration. High-temperature cycling experiments show how the heating/cooling and the hcp ↔ fcc phase transformation of the Co-matrix infl uence the stability of these phases. Neutron diffraction experiments using a high-temperature vacuum furnace show that Cr23C6 carbides are almost completely dissolved above 1250 °C, while the σ phase is still present at 1300 °C.
