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 ...

Theory of the martensitic transformation in cobalt

Physical Review B, 2001
A phenomenological theory of the martensitic fcc-hcp transformation is proposed and applied to the illustrative example of cobalt. The fcc and hcp structures are shown to result from different ordering mechanisms from a disordered polytypic structure and to be intrinsically faulted.

The martensite transformation

2004
Martensite is named after the German metallographer Adolph Martens who, in about 1890, was the first to describe its structure and formation.

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}

Martensitic transformations in alloys with martensite which ages

Metal Science and Heat Treatment, 1964
1. Molybdenum decreases the temperature interval in which martensite is formed in Fe+20% Ni alloys, while cobalt increases it. The additional elements investigated here affect the temperature interval of the martensitic transformation in the same way as that in steel. 2.

The martensitic transformation: mechanisms and crystallography

Philosophical Magazine A, 2002
Abstract The atom movements during the martensitic transformation are described by a combination of two shears: a long-wave primary and a secondary shuffle type shear which occur simultaneously. The primary and part of the secondary shear are equivalent to the Bain distortion, and the rest of the secondary shear corresponds to the lattice invariant ...
