Abstract

In order to clarify the recrystallization mechanism of low-density δ-ferrite steel Fe–4Al–2Ni, interrupted and single-pass compression tests were carried out. In this regard, five deformation temperatures (750–950 at an interval of 50 °C) and different hold time were selected. It was observed that the softening and recrystallization fraction was enhanced with increased deformation temperature and hold time. The original grain boundaries were the preferred nucleation sites for recrystallized grains, and recrystallization had an impact on obtaining homogeneous and fine-grained structure. Recrystallization in the ferritic alloy commenced after a significant degree of softening, and the softening associated with recovery was appreciably less. The optimum rolling deformation temperature was identified to be greater than 900 °C.
