5. (a) At the surface of a steel bar there is one carbon atom per 20 unit cells of iron. At 1 mm below the surface, there is one carbon atom per 30 unit cells. The diffusivity at 1000° C is 3 x 10" m/s. The structure at 1000° C is FCC (ao =0.365 nm). How many carbon atoms diffuse through each unit cell per minute?

Question

5. (a)
At the surface of a steel bar there is one carbon atom per 20 unit cells of iron. At 1 mm
below the surface, there is one carbon atom per 30 unit cells. The diffusivity at 1000° C is 3
x 10' m/s. The structure at 1000° C is FCC (ao = 0.365 nm). How many carbon atoms
diffuse through each unit cell per minute?
(b)
Explain why the phenomenon for creep is so closely related to diffusion.
(c)
Describe some general characteristics of creep resistant materials.
