Explanation:

As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it changes to its γ-iron allotrope, a face-centered cubic (fcc) crystal structure, or austenite...

Answer 2

Pure iron can have two differentcrystal structures as its temperatureis increased from room temperature to its melting point. At room temperatureit 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.
