Symmetry groups of the austenite lattice and construction of self-accommodation complexes of martensite crystals in alloys with the shape-memory effect

The internal structure of experimentally observed self-accommodation complexes of martensite crystals, which is determined by the system of twinning planes, is studied in this work. The direct correlation of the construction type of the complexes with the subgroups of the austenite lattice symmetry group is shown.
