Notes:
Factors controlling the recrystallization of a continuous cast Al-Fe-Ni alloy wereinvestigated by analyzing microstructure, grain structure, texture, and electron backscatteringpatterns. The texture of an as-rolled sample heated at 400°C was similar to that of a sample at thereduction ratio of 50% after intermediate annealing at 550°C. The as-rolled samples had a strong(213)[36-4] (S-type) orientation that was changed to a strong (130)[3-12] (QQ-type) orientation byheating at 400°C. This recrystallization looks like continuous recrystallization. Discontinuousrecrystallization due to particle-stimulated nucleation is suppressed by the fine dispersion ofAl-Fe-Ni-Si particles that form during casing and intermediate annealing, and stabilize the grain andsubgrain structure. We think that a course initial grain structure and moderate level of strain level arethe important factors promoting continuous recrystallization in this alloy
