The aim of the performed tests was to analyse the precipitation processes in the 23Cr--45Ni--6W--Nb--Ti--B (HR6W) alloy based on nickel. The examined material was subjected to the process of long-term isothermal annealing at 700 °C, for various time periods of up to 10000 h. The scope of the tests included: structural tests using scanning electron microscopy, the analysis of the precipitation processes with the use of X-ray phase analysis and electron diffraction with transmission electron microscopy. The tests showed that only MX-type precipitates occurred in the analysed alloy in the as-received condition, whereas the long-term annealing contributed to the precipitation of secondary phases of M23C6 carbides and the Laves phase.
