摘要

The final microstructure of cold rolled intermetallic disordered alloy Fe17Al4Cr0.3Zr was rebuilt during the annealing at moderate temperatures in the range of 800 to 900 °C. The time necessary to obtain recrystallized structure was determined at several annealing temperatures to optimize the processing technology of the plates. The phases present in the material during this process were identified. The grain growth (grain boundary movement) during static recrystallization (SRX) is connected with the interaction with an array of the Laves phase λ1(Fe,Al)2Zr and ZrC particles. The Avrami-based phenomenological model describing kinetics of SRX was developed. The activation energy for recrystallization was estimated.
