Effects of Austempering and Martempering Processes on ...

2010-2-1 · As the B. temperature is higher than M., the retained austenite of austempering process is considerably less than that of martempering process- "]. 3) Increasing the holding time in salt bath at temperatures below M. increases the M. temperature and decreases total amount of retained austenite slightly, because of destabilization of austenite.

Austempering - an overview | ScienceDirect Topics

9.2.6.2 Martempering (or Marquenching) Martempering involves an interrupted quench of austenitized steel to reduce the overall cooling rate. Residual stress generation in the martensite and its potential for distortion and even cracking are minimized in this way. ... Rivera et al. (2002) developed an austempering treatment directly from the as ...
