Σ3 twin boundaries and texture in FCC solid solutions and alloys with L12 superstructure

Аннотация

Crystallographic textures in solid solutions (Cu–Al, Cu–Mn) with face-centered cubic lattice, and in alloys (Ni₃Mn, Pd₃Fe) with L1₂ superstructure, are investigated by means of scanning electron microscopy with back-scattered electron diffraction. It is found that an increase in the portion of S3 twin boundaries in a special type of boundary spectrum is accompanied by a strengthening of texture.
