Metallographer's Guide: Practice and Procedures for Irons ...
At a temperature above 912 °C (1675 °F), the stable phase of iron is gamma iron,
which is a face-centered cubic (FCC) form of iron. Below 912 °C (1675 °F), alpha
iron is the stable phase and has a body-centered cubic (BCC) crystal structure.

The Metallography and Heat Treatment of
Iron and Steel
alpha state precedes its liberation from solution, three solid solutions of carbon in
iron are formed during the slow cooling of steel, namely, carbon (or the carbide
FeZC) dissolved (l) in gamma iron, (2) in beta iron, and (3) in alpha iron. The first
...

Iron and Steel Production
When, for example, a steel is heated to 1,000°C, the following changes occur in
its structure. Alpha-iron changes to gamma-iron, and the cubic lattice transforms
from body-centered into face-centered. Atoms of carbon are redistributed as the ...

5b indicate that the freestanding rods and frames were composed of iron, carbon
and oxygen, and that the diffraction indices and corresponding ring positions are
in agreement with that of alpha-iron and possible iron oxides. Iron carbides ...

Heat Treatment : Principles and Techniques
Beta (p) iron, which is a non-magnetic version of alpha iron, is identical to alpha
iron in crystal structure, and exists from 910°C to 768°C. The temperature at
which paramagnetic beta iron transforms to ferromagnetic alpha iron is termed as
...

Alpha-iron (α-Fe). Between room temperature and a transition temperature of 769
°C, pure iron exhibits a body-centered cubic (bcc) crystal lattice (a = 286.645 pm
at 25°C). Alphairon is a soft, ductile metal with a density of 7875 kg.m−3.

Construction Materials: Types, Uses and Applications
Alpha iron becomes nonmagnetic from above about 1414°F (768°C) to about
1670°F (910°C). At these temperatures it becomes gamma iron, which will hold
carbon in solid solutions up to 2% at 2066°F (1 130°C). Gamma iron is described
as ...

Chemical Engineering Reference Manual for the PE Exam
Alpha-iron is stable from —460°F to 1670°F (—273°C to 910°C), soft, and
strongly magnetic up to approximately 1410°F (766°C). (Beta-iron is a
nonmagnetic form of BCC alpha-iron that exists between 1418°F and 1670°F (
770°C and 910°C).
