An alloy of Fe in γ-Fe (FCC) with a uniform Fe concentration of 0.41 wt % is to be treated at 1050 OC. The concentration of the Fe at the surface is brought to 1.5 wt %. How long will it take (hrs) to bring the Fe concentration to 0.74 wt% at a distance of 0.35 mm below the surface? Note: get the diffusion coefficient of Fe from the tabulation of diffusion data.
