3. To decrease greenhouse gas emissions the steel industry is increasingly moving to employing the electric arc furnace (EAF) steel making route where steel scrap can be used as the source material. Here, the level of residuals is of concern with tin being an important trace element. The diffusion coefficient of Sn is an important parameter to assess the potential role of Sn on microstructure-property evolution during thermomechanical processing of steel. The Sn diffusion coefficient in fcc-Fe has been measured to be 4.910-11 cm2/s at 1000 C, 1.810-10 cm2/s at 1100 C and 5.710-10 cm2/s at 1200 C. Make an Arrhenius plot for the diffusion coefficient and determine the pre-exponential term and the activation energy for Sn diffusion. Further, estimate the heat treatment temperature for which a holding time of 2 hours would lead to a diffusion distance of 10 m
