What is the crystal structure of iron and cobalt ?

Iron in different temperature scale have different crystal structure. In the chamber ndfeb WenTie functioning centered cubic lattice, called alpha iron (alpha Fe). When the temperature plasticizing magnetic added to 912 ℃, alpha iron into a face-centered cubic lattice, called a gamma iron (gamma Fe). When the temperature increased to 1394 ℃, cobalt gamma iron into a body centered cubic lattice, known as the delta (delta Fe) of iron. The delta Fe always stick to the iron melting point (1538 ℃) into a liquid.

Ferromagnetic metal cobalt: element symbols Co, silvery white, appearance after polishing pale blue sheen, Ⅷ clan in the periodic table, atomic number 27, atomic weight of 58.9332, close the six-party crystals.
