Question

The steel contains 8.5% mass of Ni at position x of FCC iron grains and 8.8% mass of Ni at the grain boundary. The distance between the two points is 40 µm. Calculate the atomic flux between x and the boundary m. Calculate atomic flux between x and grain boundaries at 1200 ° C. (a = 0.365nm)

D0 = 1.9 x 10^-4 Qd =285,000
