Martensit und Metallographie / Martensite and Metallography
Praktische Metallographie/Practical Metallography, 2000Martensite and metallography were the two subject areas in which Hermann Schumann (1924 -1989) achieved great respect. An example of which is his work on y ↔ e -transformations, the fundamentals and technical exploitation of which he combined in the development of new materials [1]. This paper is dedicated to his memory.

The simultaneous occurrence of martensitic transformation and reversion of martensite
Materials Science and Engineering: A, 2014Abstract 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 “

Relaxation Rotation during Martensitic Transformation and Scattering of the Martensite Texture
Doklady Physics, 2023In the our crystallographic theory of martensitic transformation, a new characteristic of martensitic transformation appears – a relaxation rotation, which was not in the generally accepted phenomenological theory of martensitic transformation. The relaxation rotation is necessary to obtain an invariant plane.

Defect modelling of martensitic interfaces in plate martensite
Materials Science and Engineering: A, 2008Abstract A physical model of martensitic transformations describing the structure of the parent–martensite interface and the transformation mechanism is presented. This approach is used here to model martensitic transformations in lath and plate martensite. The habit plane comprises coherent (1 1 1) γ //(0 1 1) α terraces where the coherency strains

Influence of austenite and martensite strength on martensite morphology
Metallurgical Transactions, 1971The martensite morphology and austenite flow strength have been determined in a variety of ferrous alloys chosen so that the austenites were paramagnetic, ferromagnetic, substitutional strengthened, and interstitial strengthened. It is demonstrated that two of the most important variables in determining the habit plane (and thus morphology) of ...

Martensitic transformation of Ca
Physical Review B, 1990A 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 ...

Abstract A generalization of the phase-field theory for multivariant martensitic phase transformations is suggested that allows one to vary martensite–martensite interface energy independent of energy for austenite–martensite interfaces. The finite element method is utilized to solve the coupled phase-field and elasticity equations. Width and energy of
