Observations of VC particles in 0·5Cr–0·5Mo–0·25V steels show that the coarsening rate is generally very low. Insufficient data are available to determine the time dependence exactly so that coefficients have been calculated using a cube relationship to enable comparison with some relevant published data. The wide range of particle sizes in as-heat treated materials is emphasized. Interphase particles appear to coarsen less readily than dislocation nucleated particles.
