Austempering

Quenching a ferrous alloy from a temperature above the transformation range, in a medium having a rate of heat abstraction high enough to prevent the formation of high-temperature transformation products, and then holding the alloy, until transformation is complete. The advantages of this method of interrupted quenching are increased ductility and toughness.
