The Tapering Length of Needles in Martensite/Martensite Macrotwins
Archive for Rational Mechanics and Analysis, 2023 AbstractWe study needle formation at martensite/martensite macro interfaces in shape-memory alloys. We characterize the scaling of the energy in terms of the needle tapering length and the transformation strain, both in geometrically linear and in finite elasticity.

Building Hierarchical Martensite [PDF]
Advanced Functional Materials, 2020 AbstractMartensitic materials show a complex, hierarchical microstructure containing structural domains separated by various types of twin boundaries. Several concepts exist to describe this microstructure on each length scale, however, there is no comprehensive approach bridging the whole range from the nano‐ up to the macroscopic scale.

The Features of Martensitic Transformation in 12% Chromium Ferritic–Martensitic Steels [PDF]
Materials, 2021 An anomaly in martensitic transformation (the effect of martensitic two-peak splitting in the temperature-dependent thermal expansion coefficient) in complex alloyed 12% chromium steels Fe-12%Cr-Ni-Mo-W-Nb-V-B (ChS-139), Fe-12%Cr-Mo-W-Si-Nb-V (EP-823) and Fe-12%Cr-2%W-V-Ta-B (EK-181) was investigated in this study.

On the mechanism of martensite nucleation [PDF]
Acta Metallurgica, 1989 Abstract The martensitic transformation in the following two model systems, Fe-30 at.% Ni and In-5.25 at.% Cd, was studied by X-ray diffraction and metallography in order to answer the following question: does the nucleation of martensites occur by a soft mode mechanism or by classical heterogeneous nucleation?
