Question: the radius of the iron atom in the bcc lattice...

Question details

The radius of the iron atom in the BCC lattice is 1.24 x 10-10m. Compute the size of the octahedral interstitial site and compare with the size of a carbon atom, which has a radius of 0.77 x 10-10 m. Repeat the calculation for FCC iron lattice where the atomic radius is 1.27 x 10-10 m. From your answers in (a), comment on the degree of carbon solubility and solid solution strengthening potential in the two iron lattices. 4.5 (a) (b)
