- Co-Re-based alloys strengthened by carbides are promising candidates for new high-temperature alloys for gas turbine applications. The high temperature microstructure and its stability are of utmost importance, e.g. due to strengthening-phase selection. Neutron scattering, providing in situ information at high temperatures, was extensively used in the past for the Co-Re alloys research. The paper focuses on TaC strengthened alloy, particularly on the stability TaC precipitates which were previously shown not to dissolve up to at least 1300°C. Small-angle neutron scattering shows that its finer morphological variant - most suitable for high temperature strengthening - coarsened even at relatively low temperature of 1000°C. This coarsening is faster at higher temperatures and the mean size exceeded 1000 Å (i.e. the size - detection limit of the used facility) after 4 h hold at 1200°C.
