Modelling of nanocrystallization in Finemet-type alloy from enthalpy measurements
Description
We have studied the enthalpy changes in Fe73.5Cu1Nb3Si13.5B9 alloy along isothermal DSC runs and performed X-ray diffraction (XRD) on annealed samples. The average grain size of nanograins presents a limit nearly independent of temperature (∼12 nm). Modelling of the enthalpy variations was performed and good agreement with experiments is observed in the low temperature range. When the temperature is increased, steady-state nucleation seems to be invalid for long annealing times. A plausible explanation is presented involving the formation of a Nb diffusion layer around the nanograins. (orig.)
