Self-accommodating complexes consist of a set of\u0000pairwise twinned domains — crystals of martensite belonging to crystallographically equivalent variants of\u0000the orientation relationship between the lattices of austenite and martensite. The simplest SC are calculated\u0000for tetragonal, orthorhombic, rhombohedral and monoclinic distortion of the cubic lattice of austenite. It is\u0000shown that complete self-accommodation is possible only in complexes containing simultaneously all variants\u0000of the orientation relation.\u0000The issue of external faceting of complexes is discussed. The reason for the formation of SC is the minimization\u0000of elastic energy, i.e. the appearance regulated by the energy of the interphase boundary. On the other hand,\u0000if the outer surface of the SC is a polyhedron, then its symmetry should \"fit\"into the anisotropy of the elastic\u0000properties of austenite. For reasons of symmetry, it is clear that the polyhedron must be correct and have\u0000the same symmetry elements as the cubic lattice of austenite, while the axes of symmetry of the cubic lattice\u0000of austenite must coincide with the axes of symmetry of the polyhedron. Similar polyhedra are some of the\u0000bodies of Platon and Archimedes, which have axes of symmetry of the 2nd, 3rd and 4th order. A number of\u0000examples calculated in the work confirms the possibility of the existence of complexes in the form of these\u0000polyhedra.","PeriodicalId":399279,"journal":{"name":"Seriya 3: Fizika, Astronomiya","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126305614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
