Autocatalysis, Entropic Aspects and the Martensite Transformation Curve in Iron-Base Alloys [PDF]

Materials Research, 2017
This study advances a methodology that consolidates the description of time-dependent (isothermal) as well as time-independent (athermal) martensitic transformation curves.

Pressure-induced amorphization, crystal-crystal transformations and the memory glass effect in interacting particles in two dimensions [PDF]

, 2005
We study a model of interacting particles in two dimensions to address the relation between crystal-crystal transformations and pressure-induced amorphization.

Compositional Influence on Martensitic Transformations in Ni-Ti Alloys by Molecular Dynamics [PDF]

Materials Research
Over the last decades, high-entropy refractory alloys with shape memory (SM) effect have been increasingly studied. However, identifying the optimal composition among the vast array of potential systems remains a significant challenge for the scientific ...

Shape Change and Crystal Orientation of B19 Martensite in Equiatomic TiPd Alloy by Isobaric Test

Metals, 2020
We investigated the texture and the shape change in the equiatomic TiPd alloy, and discussed the relationship between the shape change and the atomic movements associated with martensitic transformation.

Amorphous martensite in β-Ti alloys

Nature Communications, 2018
Displacive martensitic transformations through lattice distortion usually involve a change from one crystal structure to another. Here however, the authors “melt” metastable Ti alloys during cooling and show that a martensitic transformation can lead to ...

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.

Acoustic Emissions during Structural Changes in Shape Memory Alloys

Metals, 2019
Structural changes (martensitic transformation, rearrangements of martensitic variants) in shape memory alloys have an intermittent character that is accompanied by the emission of different (thermal, acoustic, and magnetic) noises, which are ...
