A Phase Field Model for Martensitic Transformations [PDF]

PAMM, 2012
AbstractThe martensitic transformation is described using a phase field model which is in mathematical terms the regularization of a sharp interface approach. In this work, up to two martensitic orientation variants are considered. The evolution of microstructure is assumed to follow a time dependent Ginzburg‐Landau equation. The coupled problem of the

Correlation between Local Structure Distortions and Martensitic Transformation in Ni-Mn-In alloys

, 2010
The local structural distortions arising as a consequence of increasing Mn content in Ni_2Mn_1+xIn_1-x (x=0, 0.3, 0.4, 0.5 and 0.6) and its effect on martensitic transformation have been studied using Extended X-ray Absorption Fine Structure (EXAFS ...

The interplay between the martensitic transformation rate and the rate of plastic relaxation during martensitic transformation in low-carbon steel, a phase-field study

npj Computational Materials
The complex interplay between the rapid martensitic transformation and the plastic relaxation during martensitic transformation in low-carbon steel is investigated using a combined phase-field and phenomenological crystal plasticity approach.

Nondissipative Martensitic Phase Transformation after Multimillion Superelastic Cycles [PDF]

Physical Review Letters
Superelastic alloys used for stents, biomedical implants, and solid-state cooling devices rely on their reversible stress-induced martensitic transformations. These applications require the alloy to sustain high deformability over millions of cycles without failure.

Synergism between coherent precipitation strengthening and FCC-HCP type transformation-induced plasticity

Materials & Design, 2022
It is becoming a trend that many strengthening methods are applied at the same time to overcome the strength-ductility trade-off. However, the combination of precipitation strengthening and transformation-induced plasticity (TRIP) is rarely used ...
