Kinetics and Microstructural Control

· Plate martensite formation via a shear transformation and subsequent strain reduction through is twinning illustrated.
· Two shear components occur in the martensitic transformation: (a) Homogeneous shear displacements. (b) Fine scale slip within the transforming region, and fine scale twinning
