* Lattice parameter of γ-Fe is a = 0.37 nm * Diffusion coefficient D = 2.5 x 10-11 m2/s * Using the equation for diffusion coefficient: D = (1/6)α2Γ Where: α is the distance between atomic planes = a/√2 = 0.37/√2 = 0.26 nm Γ is the jump frequency * Substitute values in the equation: D = (1/6) × (0.26 nm)2 × Γ 2.5 x 10-11 m2/s = (1/6) × (0.26 x 10-9 m)2 × Γ
