What are the main differences between martempering and ...

They are both processes for tempering metals. The basic difference is the time factor. Martempering is used usually on steel to cool the metal slowly (so that it hardens evenly) whereas austempering is quite a rapid process used on many different metals.

Austempering - Wikipedia

Austempering is heat treatment that is applied to ferrous metals, most notably steel and ductile iron. In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austeniteknown as ausferrite. It is primarily used to improve mechanical properties or reduce / eliminate distortion. Austempering is defined by both the process and the resultant microstructure. Typical austempering process parameters applied to an unsuitable material will not resu

What is austempering? - Quora

Austempering – It is quenching from a temperature above the transformation range to some temperature above the upper limit of martensite formation, and holding at this temperature until the austenite is completely transformed to the desired intermediate structure, for the purpose of conferring certain mechanical properties.
