Abstract

The alloy Mn-Al-C (magnetic τ-phase) has a face-centered tetragonal lattice with the superstructure L10 (Shangurov, Gornostyrev, Teitel et al., 1990). The tetragonal crystal axes c (the directions of the easy magnetization) of the grain lattices of the polycrystal permanent magnet must be preferably oriented along the magnet axis. In the present paper the forming of the axial extrusion textures in the alloy Mn-Al-C is investigated theoretically. The texture inhomogeneity is taken into account by solving the boundary value problem of plasticity.
