Dear all,<br> <br> I am calculating the substitutional formation energy of Ni- based system to study the partitioning behavior of the alloying elements. this just means that i need to find the preferential position of alloying element within the system based on the minimizing the total energy of the system. there i need to calculate the chemical potential of elements such as Ni, Al, W etc. can any body suggest how to calculate it or is it the same as energy per atom of the bulk structure. <br>
<br> Also if i am studying FCC system then, for e.g. W, do i need to calculate the energy for stable BCC W or i should do calculation for FCC W. <br><br>regards<br><br>vicky singh <br>Research student<br>Bangalore<br>
