Kinetics of nanoscale precipitation in Ni–Fe–Al alloys: A magnetic monitoring approach

Microalloying effects on the microstructure and kinetics of nanoscale precipitation in Ni–Al–Fe alloy

“…The calculated Avrami time exponents range between n ¼ 0.8 and 1, showing no clear discrepancy with the type of quaternary addition. In our previous study [40], it was found that the precipitation of a-phase in the b-matrix was predominated by diffusion controlled growth without a change in mechanism throughout the entire measurement time. ably low E a deduced from the kinetic analysis could be due to a process where growth of already nucleated phase occurs.…”
