"In the development of new high-temperature alloys for gas turbine applications various candidates are under consideration. This contribution deals with a CoRe based alloy strengthened by Cr23C6 type carbide and Cr2Re3 type phase precipitations (here designated as CoRe-1 alloy). High-temperature cycling experiments show how the influence of heating, cooling and the hcp <-> fcc phase transformation of the Co-matrix on the stability of these phases. Neutron diffraction experiments with high-temperature vacuum furnace show that Cr23C6 carbides starts to dissolve around 1100 degrees C and above 1250 degrees C are almost completely dissolved. On the other hand sigma phase is still present at 1300 degrees C. This contribution describes the evolution of the different phases during the heating and cooling cycles which are repeated two times. Further, the influence of boron addition to CoRe-1 alloy was studied for samples in the first heating/cooling cycle. A newly developed tensile rig was also tested up to 980 degrees C to combine in situ loading and heating for the neutron diffraction measurements." .
