URGENT PLS HELP!!
Nitrogen from a gaseous phase is to be diffused into pure iron
at 700°C. If the surface
concentration is maintained at 0.1 wt% N. The nitrogen diffusion in
BCC iron follows the interstitial
diffusion mechanism with the pre-exponential parameter 0.17×10−5
m2/s and the activation
energy 90 kJ/mol. What will be the concentration at 1 mm from the
surface after 10 h?
