Martensite - austenite transformation.
martaust.mov (~2.0Mb) |
Martensite - austenite transformation via the motion of invariant walls oriented perpendicular to [100] B2 and [010]B2 bands. Note the herringbone pattern in the wake of the moving invariant wall. |
Reverse transormation of Martensite.
revtrans.mov (~2.5Mb) |
Reverse transformation dynamics for a sample aged at room termperature involving the sequential reverse transformation of island areas of martensite. |
