Multi-stage phase transformation pathways in MAX phases [PDF]

Nature Communications
Diverse, multi-stage phase transformations occur in many materials under extreme environments. In response to irradiation, some MAX phase compositions transform from an initial hexagonal structure to an intermediate γ-phase, then to a face-centered cubic

Continuous-phase-transformation acoustic metasurface

Results in Physics, 2021
Acoustic metasurfaces are artificial structures, one of whose functions is to achieve plane wave focusing due to the phase gradient transformation of specific structural units. However, previous periodic acoustic metasurfaces for plane wave focusing have

Stress-Induced Phase Transformations in Shape-Memory Polycrystals [PDF]

, 2008
Shape-memory alloys undergo a solid-to-solid phase transformation involving a change of crystal structure. We examine model problems in the scalar setting motivated by the situation when this transformation is induced by the application of stress in a ...
