Steels and low carbon iron alloys are by far the most, Ask an Expert

Engineering

Steels and low carbon iron alloys are by far the most common metals in industrial use. The main element of these materials is iron (Fe). Fe has a BCC crystal structure.

a) Show for Fe the unit cell edge length a and the atomic radius R are related through a = 4R/?¯3.

b) Show that the atomic packing factor for Fe is 0.68.

c) Calculate the radius of a Fe atom, given that BCC Fe has a density of 7.87 g/cm³, and an atomic weight of 56 g/mol.

d) When Fe is heated to 1394 °C, the BCC crystal structure changes to FCC structure. What is the density of FCC Fe?
