The diffusivity of C in α-ferrite (BCC iron) and diffusivity of C in γ-austenite (FCC iron) is given at two temperatures (6 points): a) Calculate the activation energy of diffusion for C in α−Fe [2] b) Calculate the activation energy of diffusion for C in γ−Fe( J/mol) ? [2] c) Explain why the diffusivity of C in α - Fe is higher than the diffusivity of C in γ−Fe.
