A Typical Austempering Cyde

lina A • B shows the heat-up from room temperatura to the Austenifizing temperaturę,

while B ■ C shows the Austenitizing process, where the component is held at the high temperatura until the metal matrix fully transforms into Austenite, and is saturated with carbon.

From point C to point D, the part is rapidly ąuenched down to the Austempering temperatura. This temperatura is abore the martensite start (MS) temperaturo, and the guench takes place rapidly enough to avoid the formation of pearlite.

Linę D • E shows the Austempering process, during which the metal metru begins to transform into its finał Ausferrite matni.

Linę E ■ F shows the removal of the component from the ąuench, and cooling to room temperatura.
