Mechanics based design of structures and machines, 2020
In this article, we investigated the effect of martensite morphology on the mechanical properties and formability of dual phase steels. At first, three heat treatment cycles were subjected to a low-carbon steel to produce ferrite–martensite ...

Undesirable fracture resistance has led to critical safety concerns in ultra-high strength quenching and partitioning (Q&P) steels. The present work proposes a new heat treatment method of tailoring simultaneously martensite matrix and retained austenite

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.

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 “

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

A low-alloy high-carbon martensite steel with 2.6 GPa tensile strength and good ductility
Acta Materialia, 2018A low-alloy and high-carbon martensite steel (0.66% C) with ultrafine grains is produced by combination of Tempforming (tempering and deforming of a quenched steel) and reheating followed by water quenching and low temperature tempering.

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 ...

Martensit und Metallographie / Martensite and Metallography
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.

Martensitic transformations in alloys with martensite which ages
Metal Science and Heat Treatment, 19641. 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.
