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.

Why are high strength steels more susceptible to hydrogen related damage than soft and ductile metals?

Hydrogen absorption in steel lead to embrittlement by forming gas molecules or brittle phases. Why we are more concerned about high strength steel than low strength steel?

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...
