The face centered cubic (FCC) unit cell begins with a totally different layer, one that is packed much more efficiently. This figure shows the basic layer that will be repeated throughout the entire ...

It melts at 3727 C. The stable form of carbon at room temperature is Graphite ... (Lower diagram) The diamond cubic structure is a face-centered-cubic lattice with a basis of two carbon atoms.

At room temperature it is body-centered cubic, between 912 and 1394 C if is face- centered cubic, and between 1394 and its melting point at 1538 C it returns to body-centered cubic. Low carbon steel ...
