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 ...

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 alloys have a composition close to the Eutectoid ...

It melts at 3727 C. The stable form of carbon at room temperature is Graphite which has a hexagonal crystal structure. (Top diagram) Diamond is metastable at room temperature and has a diamond cubic ...
