Abstract

The cold-rolled and recrystallization textures of Fe-Cr-Co-Mo permanent magnet alloys are described. The studied composition is Fe-30%Cr-15%Co-3%Mo (in wt%). The cold-rolled texture can be considered as {111}<110>, {111}<112>, {100}<110>, and {211}<110>, while the recrystallization texture can be considered as {111} <110>, {110}<112>, {211}<110>, and {110}<110>. The secondary recrystallization is caused by heat-treating the alloys in the sequence of a, a + y, a + y + a, a phase region (HTSR). This results in a favorable texture of {110} <110> and <100> direction, aligning along the transverse direction (TD) of the strips. The best magnetic properties obtained in this study are Br = 1.2 T (12.0 kG), iHc = 82.0 kAm–1 (1025 Oe), and (BH)max = 60.8 kJm–3 (7.6 MGOe) with TD alloys.
