Question:
At 913˚C, Iron is FCC; while at 911 ˚C, Fe is BCC. While transforming from FCC to BCC, should the Fe contract or expand and by how much in percentage? (Consider the hard sphere model for your calculations). (Hint: The lattice parameter of FCC is greater than BCC iron). (b)What will be the crystal structure of amorphous iron at exactly 912 ˚C?
