The mechanical properties of hardened AISI 52100 bearing steel such as flexural strength,
microhardness and Young's modulus are considerably influenced by the austenite content …

The present work develops a numerical approach combining thermodynamic and kinetic
simulations to investigate the austenitisation process on spheroidised bearing steel. The …

The amounts of retained austenite in the powder high-speed steel GPM A30 were calculated
using a Rietveld computer model, and the relationship between the microstructure and …

Bearing steels are heat treated to get martensitic microstructures providing high hardness
necessary for good rolling contact fatigue performance. Without specific action taken …

The toughness of high-strength steels is improved when their martensitic matrix is combined
with the presence of retained austenite. The stability of retained austenite is crucial, both …

In situ neutron diffraction of the uniaxial tension test was used to study the effect of the
surrounding matrix microstructure on the mechanical stability of retained austenite in high …

The mechanical stability of retained austenite is explored in martensitic bearing steels under
cyclic compressive stresses up to∼ 10 6 cycles at 3 GPa, combining X-ray diffraction and …

Micromechanically-based models are used to mimic the martensitic phase transformations
in retained austenite and the elasto-plastic behavior of the adjacent ferritic phase. The …

Untransformed austenite during quenching process is known as retained austeinite. The
quantitative determination of the retained austenite is of great importance to the steel …

Thermomechanical processing (TMP) of microalloyed steels has been shown to produce
refined microstructures by austenite grain boundary pinning and elevation of the austenite …
