Iron goes from a face-centered cubic (FCC) structure—the gamma phase, or austenite—at high temperatures to a body-centered cubic ... Others alter or reduce the grain size or their pattern ...

At room temperature it is body-centered cubic, between 912 and 1394 C if is face- centered cubic, and between 1394 and its melting point at 1538 C it returns to body-centered cubic. Low carbon steel ...

At room temperatures and normal atmospheric pressure, iron is in what is known as a body-centered cubic (BCC ... that is directional -- like the grain of wood. Anisotropy explains why seismic ...
