Using differential scanning calorimetry, we have examined the effect of isotopic composition on the temperature and kinetics of the α → γ phase transition of isotopically natural (
nat
Fe),
56
Fe-enriched, and
57
Fe-enriched Fe samples and assessed kinetic phase transition parameters as functions of isotopic disorder parameter. A time–temperature–transition diagram is presented for the fraction of the γ-phase resulting from the α → γ phase transition.
