Existing experimental results have shown that multi-step martensite transformation can be induced by the applied stress in single crystal NiMnGa ferromagnetic shape memory alloys (FSMAs) and the transformation property depends on the ambient temperature strongly. In this work, a crystal-plastici...detailed
The effect of alloying element Zn on the characteristics of thermal induced martensite and magnetic properties of martensite phase were investigated with scanning electron microscopy (SEM) and Mössbauer spectroscopy characterization techniques. SEM observations revealed that the athermal martens...detailed
The influence of the chemical composition of a NiTi alloy on the martensite stabilization effect was studied. The Ni- 50.0 at. %Ti, Ni – 49.5 at. % Ti and Ni – 49.0 at. %Ti alloys were quenched from 900 °C (10 min) into water and after this heat treatment, the alloys underwent the B2 ↔ B19′ ...detailed
Lath martensite is widely present in advanced high strength steels as the key strengthening phase. Unexpectedly high ductility of lath martensite has been reported in the literature in both single-phase and multi-phase steels, however, without systematic identification of the underlying plastici...detailed
We present three-dimensional phase-field simulations of martensite microstructure formation in low-carbon steel. In this study, a full set of 24 Kurdjumov-Sachs symmetry variants of martensite is considered. Three different carbon compositions are investigated in order to reveal the effect of ca...detailed
This work generalizes the geometric non-linear, phenomenological theory of martensite crystallography, a time-proven model for the description of martensitic microstructures. Particularly, the case of reconstructive lattice transformation associated with slip is treated as opposed to displacive ...detailed
