Calculating Extrusion Textures of the Alloy Mn‐Al‐C

Abstract

The alloy Mn-A1-C (magnetic z-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-A1-C is investigated theoretically. The texture inhomogeneity is taken into account by solving the boundary value problem of plasticity.

“…and twin systems {111}(112) (Shangurov et al, 1990). The present authors (Solovei and Loginov, 1996) suggest that the deformation textures in the alloy Mn-A1-C can be calculated only with the slip systems { 111 } (110), { 111 }(101) and the twin systems { 111 }(112). They also assume that the critical resolved stresses for all the slip systems are equal and that the critical resolved stresses for the twin and slip systems are connected by the relation -t 0.6-s.…”
