Austemper

Heat treating to provide uniform structure through out material and used to produce Ѵ®

The Ƶ austempering process provides a solution to the expansion problems inherent with conventional quench and temper heat treating. Austempering produces its hardened structure (bainite) gradually and at a relatively high temperature, which provides many advantages. First, bainite’s slow nucleation and growth allows the transformation stresses to dissipate (20-minute bainitic reaction versus instantaneous martensitic reaction). Second, there is an increased plasticity resultant from the relatively high temperatures in the bainite transformation stages. Third, a smaller volume change is associated with the transformation to bainite. Further, bainite is more ductile than untempered martensite.
