Diffusion in Solids

Click here to download the CDF file for use offline.

The mole percentage of a solute in a semi-infinite solid block is calculated as a function of distance from the surface. Carbon and copper are the diffusing species and their surface concentrations are fixed using a slider. Display the diffusing systems by checking the boxes for carbon into iron (C into Fe), copper into aluminum (Cu into Al), and copper into nickel (Cu into Ni). Use the sliders to vary the temperature of the block and the diffusion time.
