Structure of rolled ferrite alloyed with 9.3 wt.% Al and 0.5 wt.% Zr

Abstract

The previous experiments had shown that the rolling temperatures of iron aluminides based on Fe3Al must be about 1200 °C to initiate the softening during and between individual passes. Material with lower content of aluminium (outside the phase field of iron aluminides) was tested in the laboratory rolling process, because the lower rolling forces are expected for the disordered lattice. Zirconium additions are expected to enhance the strength of the material for any practical use at higher temperatures.
