Discontinuous coarsening of lamellar cellular precipitate in an austenitic Fe-30 wt.%Ni-6 wt.%Ti alloy—II. Growth kinetics

The growth kinetics of discontinuous coarsening of lamellar cellular precipitate in an austenitic Fe-30 wt.%Ni-6 wt.%Ti Alloy aged at temperatures ranging from 400 to 900°C have been studied by light and electron microscopy measurements of cell growth rate and lamellar spacing. Analysis of the growth kinetics shows that the Livingston-Cahn [1] model is not obeyed with the reason being that not all of the available volume free energy is used in...
