“…In most investigations on metals, such as aluminum and low-carbon steels, the Avrami exponent n deviates from theoretical predictions [24,25]. Heterogeneous nucleation, anisotropic nucleus growth and varying growth rates contribute to the deviation of n from the ideal value.…”

“…3,12,[17][18][19] Recrystallized fraction is generally determined in the laboratory by metallographic observations, which are time consuming and often rather subjective, or by hardness measurements. Although hardness has provided good estimations of the recrystallized fractions in some extra low carbon (ELC) steels, 3,20,21) in others (including IF steels) the mechanical softening significantly deviated from the recrystallized fraction. 12,20,22,23) Higher softening fractions than recrystallized fractions are generally attributed to recovery concurrent with recrystallization.…”

The sensitivity and limitations of magnetic coercive field, hardness, metallographic measurements and electron back scattered diffraction analysis are studied and discussed in terms of monitoring recovery and the onset and evolution of recrystallization in a cold rolled low carbon steel. The magnetic coercive field shows much higher resolution than hardness measurements when measuring recovery. Hardness is almost insensitive to the microstructural changes taking place in the material during annealing treatments performed at low temperatures. The conditions under which the magnetic coercive field measurements can also be used to monitor recrystallized fraction are also discussed.

“…However, in many cases, it has been observed that nucleation distributes heterogeneously through the material. [52] Moreover, numerical models that consider nucleation rate as a function of local deformation show better agreement with experimental results. [53] For a heterogeneous distribution of stored energy, two scenarios are possible: site saturation and continuous nucleation conditions.…”

A new analytic method based on the microstructural path method with nucleation rate and growth rate as descriptors is proposed, which provides a link between the nonhomogeneous distribution of stored energy in plastically deformed materials and the recrystallization rate. The proposed approach uses easily measured recrystallization rates to provide information about the deformation history and the inhomogeneity of stored energy. The theory was evaluated by comparing direct differential scanning calorimetry measurements of inhomogeneity factor, m, on deformed samples of pure Cu at 498 K (225°C), to those extracted from hardness measurements. Excellent agreement between the model and the experiment was found. In addition, it is shown how any given probability function describing the initial distribution of stored energy can be used to predict the evolution of the residual stored energy as recrystallization proceeds.
