Theory and Model for Martensitic Transformations [PDF]

Physical Review Letters, 1986
Martensitic transformations are shown to be driven by the interplay between two fluctuating strain components. No soft mode is needed, but a central peak occurs representing the dynamics of strain clusters.

Crystal symmetry and the reversibility of martensitic transformations [PDF]

Nature, 2004
Martensitic transformations are diffusionless, solid-to-solid phase transitions, and have been observed in metals, alloys, ceramics and proteins1, 2. They are characterized by a rapid change of crystal structure, accompanied by the development of a rich ...
