Does vacancy diffusion follow Fick's law ?

One of the irradiation induced defect, vacancy, accumulating to form void is by diffusion based mechanism. By Fick's law, a void would disintegrate to form vacancies with time. But, vacancies...

How can I get stress/strain contour/distribution of atoms deformed using Molecular dynamics tool (LAMMPS)?

I have deformed a system with a crack. I want the stress(strain) contour/distribution of the system at a given timestep. I have attached a sample image similar to which I expect a contour.

In martensitic transformation in steel, why should we consider BCT by joining the face centered atoms of FCC even though FCC has higher symmetry?

FCC has 3 fold symmetry but BCT doesn't. So why should we draw a BCT inside a FCC and name it as martensite. A reverse can also be done where we can draw BCT and they get a FCC out of it. If so in...
