Definitions for "Gamma Iron"
The allotropic form of iron existing between the temperature 910°C and 1400°C is known as Gamma Iron. It has a face centered cubic lattice and is non-magnetic. Gamma iron containing carbon or other elements in solution is known as austenite.
The non-magnetic form of iron, stable above the transformation temperature; characterized by a face-centered cubic crystal structure.
Face-centered iron, generally speaking above 1333° F.
