Abstract
The MC precipitate size distributions have been measured for times of 1, 10, 100, 300 and 1000 h at 700 and 900 C in a 16Ni-14Cr advanced austenitic steel. A new correlation between the mean precipitate size, aging time and temperature has been developed. The new correlation is compatible with a solute exhaustion mechanism, which may explain why (i) the MC precipitates formed on matrix dislocations resist coarsening for up to 3000 h at 900 C; and (ii) the degree of cold work (i.e. the dislocation density), which determines the number of MC nucleation sites, controls the limiting precipitate size.
