Martensitic transformation of pure iron at a grain boundary: Atomistic evidence for a two-step Kurdjumov-Sachs–Pitsch pathway

AIP Advances, 2016
Using classical molecular dynamics simulations and the Meyer-Entel interaction potential, we study the martensitic transformation pathway in a pure iron bi-crystal containing a symmetric tilt grain boundary.

Precursor Phenomena of Martensitic Phase Transformation

Materials Transactions, JIM, 1992
The unique aspect of martensitic transformation is pointed out to lie in coexistence of apparently contradictory features of «non-locality» and «discreteness» during the ordering process. As a remarkable manifestation of this unique feature, the precursor phenomenon called «ghost lattice effect» observed in X-ray diffraction experiments is discussed ...

Disorder-Driven Pretransitional Tweed in Martensitic Transformations

, 1995
Defying the conventional wisdom regarding first--order transitions, {\it solid--solid displacive transformations} are often accompanied by pronounced pretransitional phenomena.

Topology and Martensitic Phase Transformations

Triply periodic minimal surfaces (TPMS) are discovered to conform to surfaces of given charge density distributions embedded in crystals [Z. Kristallogr. \textbf{170}, 138 (1985)]. Based on our previous work [Phys. Rev. Mater. \textbf{9}, 073802 (2025)], we discovered that crystals can have surfaces of a given charge density converging to TPMS. We also

Phase stability and magnetic-field-induced martensitic transformation in Mn-rich NiMnSn alloys

AIP Advances, 2012
A series of Ni50-xMn41+xSn9 (x = 0–19) alloys from Ni-rich to Mn-rich composition were prepared, and the composition dependence of phase transitions and magnetic properties were investigated. No γ-phase can be observed until x = 17.

Magnetic interactions in the Martensitic phase of Mn rich Ni-Mn-In shape memory alloys

, 2013
The magnetic properties of Mn$_{2}$Ni$_{(1+x)}$In$_{(1-x)}$ ($x$ = 0.5, 0.6, 0.7) and Mn$_{(2-y)}$Ni$_{(1.6+y)}$In$_{0.4}$ ($y$ = -0.08, -0.04, 0.04, 0.08) shape memory alloys have been studied.

Temperature driven $\alpha$ to $\beta$ phase-transformation in Ti, Zr and Hf from first principles theory combined with lattice dynamics

, 2011
Lattice dynamical methods used to predict phase transformations in crystals typically deal with harmonic phonon spectra and are therefore not applicable in important situations where one of the competing crystal structures is unstable in the harmonic ...

Influence of β-Stabilizing Nb on Phase Stability and Phase Transformation in Ti-Zr Shape Memory Alloys: From the Viewpoint of the First-Principles Calculation

Metals
In the present study, the effect of the Nb element on the lattice parameters, phase stability and martensitic transformation behaviors of Ti-Zr-based shape memory alloys was extensively investigated using the first-principles calculation.
