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 ...

This single layer is the precursor of the body centered cubic (BCC) unit cell. The lattice points are in the same general form as the simple cubic (SC) unit cell, with the exception that the atoms are ...

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 ...

The transition that determines the micro-structure of the alloy is a solid-state process: Austenite <-> Ferrite + Cementite Austenite is stable above 727 C and is an interstitial solid solution of ...
