The solute enrichment of the austenite particles may be a factor contributing to the low Ms of the particles, but it does not fully account for the high austenite thermal stability. The presence of a high dislocation density within the austenite particles suggests that the stability of these particles may have substructural as well as chemical origins. Some stability of the austenite particles may be probably due to increased difficulty in propagating the shear of the martensitic transformation via ncreased barriers afforded by the substructure in the austenite particles.
