Temperature–pressure-induced solid–solid 〈100〉 to 〈110〉 reorientation in FCC metallic nanowire

 I would like to share our recent research work on FCC metallic nanowires, which is published in Journal of Physics : Condensed Matters (IOP) . The abstract of the paper is given below. Further details can be found at

Abstract: 

Stress-induced martenstic phase transformation in Cu-Zr nanowires

Hi Friends

I want to share some of our recent research work on the stress induced phase transformation of CuZr nanowire which is published in Materials Letters.

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

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

Choose a channel featured in the header of iMechanica: 

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?
