D=f(A,t)
(6.13)
where A is the atom content, D is the diffusion coefficient and t is time.
Method 3
Diffusion coefficient is a function of temperature and atom content (Tabular
format).
D=C1(T)exp(C2(T)A)
(6.14)
where
D = Diffusion coefficient
A = Atom content
C1 = Coefficient 1 which is a function of temperature
C2 = Coefficient 2 which is a function of temperature
T = Absolute temperature
Method 4
Diffusion coefficient is a function of temperature and atom content (Tabular
format).
D=C1(A)exp(C2(A)/T)
(6.15)
where
D = Diffusion coefficient
A = Atom content
C1 = Coefficient 1 which is a function of atom content
C2 = Coefficient 2 which is a function of atom content
T = Absolute temperature
