One-Dimensional Model of Interdiffusion between Two-Phase Alloys

One-Dimensional Model of Interdiffusion between Two-Phase Alloys 

It is necessary to find, by numerical methods, the diffusion path and profiles Ci (t, x), PiiiyX), p(t,x), and k(t, x) if the phase diagram and the dependence Mfk.pa) are known [51]. Here we proceed as follows. 

The diffusion couple is supposed to consist of two-phase alloys, L(c, c ) and 

In this simplified model we shall consider the diffusion of B and C 

We consider that all the conodes continue and meet each other in the apex 3 of concentration triangle, so that for the equal phase boundaries points (lying on one and the same conode) the following equations are valid.
