Describing the Kinetics of Abnormal Grain Growth in Nanocrystalline and Submicrocrystalline Nickel, Based on First-Order Phase Transition Representations

Resumo

The growth of grains in nano- and submicrocrystalline nickel produced via equal channel angular pressing is investigated under conditions of non-isothermal annealing using differential scanning calorimetry and transmission electron microscopy. Both types of the material exhibit abnormal grain growth that can be described in terms of the Johnson–Mehl–Avrami formalism.
