4. Crystal Structure
Face Centred Cubic Structure
Body Centred Cubic Structure
Hexagonal Closed-packed Structure
5. Face Centered Cubic Structure
The face centered cubic arrangements
has fourteen(14) atoms
The atom are arranged at the corners
and center of each face of the cell
6. Face Centered Cubic Structure
Atoms are assumed to touch along
face diagonals
10. Atomic packing factor(APF)
It can be defined as the ratio between
the volume of the basic atoms of the
unit cell (which represent the volume
of all atoms in one unit cell ) to the
volume of the unit cell it self.
12. Characteristics of FCC
They are plastic and malleable.
It,s stronger and denser than BCC.
Atoms are arranged at the corners and center of each cube face of the cell.
13. Examples
Metals with the FCC Structured include
Aluminum
copper
nickel
iron,
gold
silver
