Special Issue in Crystals: Crystallography of Structural Phase Transformations (Volume II)
Solid-solid phase transformations generally imply a crystallographic orientation relationship (OR). The precipitates at the nucleation stage are often in OR with the surrounding matrix; the martensite products are in OR with their parent austenite; and the annealing twins and deformation twins are two crystals of the same species linked by an OR. The symmetries of the phases combined with the OR generate complex microstructures made of variants or twins that can be described mathematically with group theory, linear algebra, coset and multiple cosets, graphs, groupoids, or high-dimension spaces, etc. A lot of efforts have been devoted over the last century to establishing bridges between this “descriptive” crystallography and the “predictive” thermodynamics, but full unification remains to be achieved. For the moment, the models are not well balanced. On the crystallographic side, the phenomenological of theory of martensitic crystallography (PTMC), the edge-to-edge matching model, the disconnection “topological” model, etc. are well developed, but they are often limited to using the generalized Clausius–Clapeyron formula to make the link with thermodynamics. On the thermodynamic side, one can find the famous Landau and Ginzburg–Landau theories, but crystallographic complexity is often reduced to the symmetries of the polynomial form of the free energy introduced with group representation theory. It is not easy to find a way to marry all the different approaches, even if phase field has made a lot of progress over the last decades.
As it is important for research in this field to continue, all experimental and theoretical contributions about phase transformations and crystallography are welcome in this Special Issue, regardless of the type of materials (piezo and ferroelectrics, structurally hardened alloys, martensitic alloys, ordered alloys, shape memory alloys, polymorphic minerals, mechanically twinned materials, etc).

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
