Martensitic transformation of Ca

Physical Review B, 1990
A la temperature ambiante, Ca subit une transformation structurale induite par la pression de 20 GaPa, passant de la structure cubique a faces centrees a cubique centre. On examine un modele de distorsion pour cette transformation. Le mecanisme de Bain est un cas particulier de la distorsion triclinique plus generale, et des lors qu'un chemin dans cet ...

Martensitic Transformations in Bochum

Angewandte Chemie, 1989
Conference Reports: Martensitic transformations are first order structural phase transformations which occur in a range of crystalline solids. A recent meeting in this field in Bochum, FRG, is reviewed by N. Jost while W. Kaysser reports that Las Vegas was the scene of a conference on particle technology.

The crystallography of martensite transformations II

Acta Metallurgica, 1954
Abstract The hypothesis advanced in Part I requires that the total strain in a martensite transformation be such that a twinning direction in the final structure lie in an unrotated plane and the twinning plane contain an unrotated line of the strain. From these conditions, together with the correspondence, and the dimensions of the initial and final

Martensitic Transformations in Constrained Films

Journal de Physique IV (Proceedings), 2002
The evolution of martensitic microstructure and stress in a constrained film coupled with a substrate under cooling and heating is considered. Thermodynamic analysis has done using the special phase diagrams constructed in coordinates temperature-film/ substrate misfit.

Thermodynamics of Thermoelastic Martensitic Transformations

Materials Science Forum, 1989
Abstract A fundamental thermodynamic equation is derived for thermoelastic martensitic transformations. It describes the mutual equilibrium between the two phases at every temperature and applied stress, taking into account internal interaction between domains, the existence of interfaces and dissipative effects associated with motion of boundaries ...

Fluctuationless mechanism for martensitic transformations

Physical Review B, 1993
A fluctuationless mechanism for martensitic transformations consisting of the appearance and development of a lattice instability triggered by defects is presented. A number of properties associated with martensitic transformations are qualitatively explained. As a quantitative example, the theory of the displacive \ensuremath{\beta}-\ensuremath{\omega}

The simultaneous occurrence of martensitic transformation and reversion of martensite

Materials Science and Engineering: A, 2014
Abstract We use a 3D elastoplastic phase-field model to study the simultaneous occurrence of martensitic transformation as well as the reversion of martensite in steels under uni-axial tension. Our results show that although martensite nucleates and grows as a single lath (variant), it reverts and splits into two independent martensite laths, due to “
