Nanoindentation of the a and c domains in a tetragonal BaTiO3 single crystal

Submitted by Xiaodong Li on Fri, 2007-12-28 20:18.

Can we map the eastic modulus of a and c domians? Can we mechanically switch the domains and let them function as nanoactuators and sensors?

Lath martensite

Submitted by Farshid on Wed, 2007-06-27 03:32.

Does any one knows a good reference about lath martensite?

Why we see the retained austenite? why doesn't it transformto martensite? What's its effect on the phase transformation? Does the plasticity change the morphology of the transfromation? How about the speed of the transfromation? When should we expect to see the lath martensite? What's the effect of the diagonal terms in the transformation matrix? What's the effect of the shear components? Is there any difference between 2d and 3d simulations, and which one is more realistic?
