A component made from Fe - 2. at % C alloy that is about 5 mm thick is heated to 1200 K in a gaseous atmosphere that creates a fixed composition of 1 atom % C on the surface. The component is held at 1200 K for 92605 seconds before the component is removed from the furnace and cooled to room temperature, ready for subsequent processing. At this temperature (1200 K) the diffusion coefficient for carbon in the y-Fe is about 2.2x10% mm /s. (a.) On a set of axes for atom% C on the ordinate (y-axis) and for x, distance (mm) from the surface, on the abscissa, plot and label the initial condition for this diffusion process (decarburization) and describe the initial condition in mathematical symbols. (b.) Also, on the axes used to answer part (a.), mark and label two boundary conditions for the diffusion process and describe the boundary conditions in mathematical symbols
