FeRh ground state and martensitic transformation

Physical Review B, 2018
Cubic B2 FeRh exhibits a metamagnetic transition [(111) antiferromagnet (AFM) to ferromagnet (FM)] around 353 K and remains structurally stable at higher temperatures. However, the calculated zero-Kelvin phonons of AFM FeRh exhibit imaginary modes at M-points in the Brillouin zone, indicating a premartensitic instability, which is a precursor to a ...

Crystallographical Analysis on Martensite Transformation and Martensitic Morphology.

ISIJ International, 1997
The strain tensor and displacement vector associated with lattice deformation were introduced to discuss the effect of self-accommodation and plastic accommodation in martensitic transformation and the crystallographic models for {557} f , {225} f and {31015} f martensite were proposed, along with their experimental verification.
