To All,
When we talk of phases we mean different crystallographic structures. Iron
(alpha) at room temperature is BCC, body centered cubic. Iron (gamma) above
the critical point or 300 series SS is FCC, face centered cubic. Alpha
titanium is HCP, hexagonal close packed. Beta titanium is body centered
cubic. The different structures impart different characteristics.
Phases can also mean the multiple phases in iron. Alpha iron and iron carbide
are the two phases in HRS. Also ferrite and pearlite are the two phases
present which are just how the alpha iron and carbide ordered in the
structure.
