What is Austempering? - wise-geek

In the first part of the austempering process, the metal is heated to a temperature of between 1,350° F (about 732° C) and 2,462° F (about 1,394° C). This causes it to undergo a phase transition that changes the crystalline structure where the iron atoms are arranged, turning it into austenite.
