Abstract
The MC precipitate size distributions have been measured for times of 1, 10, 100, 300 and 1000 hr 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 hr at 900°C; and (ii) the degree of cold work (i.e., the dislocation density), which determines the number ofMC nucleation sites, controls the limiting precipitate size.
