Stability of retained austenite and work hardening behavior in ultra-fine medium carbon bainitic steel [PDF]
The effect of retained austenite stability on plastic deformation was investigated by stepwise tensile test of medium carbon steel material at two different bainite isothermal temperatures below or above the martensite start (Ms) point.

Characterization of Retained Austenite in Advanced High-Strength Steel. [PDF]
The retained austenite (RA) in advanced high-strength steels directly affects their plasticity. It is very important for the accurate characterization of their content and types. This paper prepared three specimens with three different Mn contents (1.0%, 1.4%, and 1.7%) that are used to obtain high-strength steel by ultrafast cooling heat treatment ...

Volume fraction of retained austenite in 1.2842 tool steel as a function of tempering temperature
Untransformed austenite during quenching process is known as retained austeinite. The quantitative determination of the retained austenite is of great importance to the steel mechanical properties.

The effect of retained austenite on the wear mechanism of bainitic ductile iron under impact load
The effect of retained austenite on the impact wear resistance of bainitic ductile iron is studied. Two kinds of bainitic ductile iron with different morphologies of retained austenite were fabricated via continuous cooling process.

Influence of cooling conditions and amount of retained austenite on the fracture of austempered ductile iron [PDF]
SEM Analysis of fracture surfaces from tensile test specimens of thick-walled, austempered ductile irons (diameter 160 mm) shows different fracture behavior depending on the austenite retained in the matrix.
