(a) Calculate the radius of the largest interstitial void in the BCC _ iron lattice. The atomic radius of the iron atom in this lattice is 0.124 nm, and the largest interstitial voids occur at the ( _1 4 , _1 2 , 0); ( _1 2 , _3 4 , 0); ( _3 4 , _1 2 , 0); ( _1 2 , _1 4 , 0), etc., -type positions. (b) If an iron atom occupies this interstitial void, how many iron atom neighbors will it have, or in other words, what will its coordination number be?
