Theory and significance of retained austenite in steels
… leading to the retention of small quantities of austenite following the bainite and martensite phase transformations have been examined, together with the influence of retained austenite on the properties of low alloy steels. It was found that the upper and lower bainite transformations are …

Hydrogen in Austenite: What Changes after Martensitic Transformation?
… Hydrogen has much lower diffusivity in austenite than in ferrite. Therefore, austenite is relatively immune to embrittlement. However, the poor stability of austenite can lead to martensitic transformation. And martensite cannot dissolve all the hydrogen inherited from austenite due to …

The Thermal Stabilisation of Austenite at Sub-Zero Temperatures
… relating to the thermal stabilisation of austenite has been reviewed with particular reference to the mechanisms proposed by various workers to account for the phenomenon. The complex interactions between martensite transformation and stress have also been discussed in order to assess the …

High-strength transformation-induced plasticity steels with reverted interlath austenite
The interlath austenite formed by reversion process increases the ductility of the martensitic steels. However, the reversion process requires high annealing temperatures and long annealing times, which lead to high energy cost and unwanted softening. In this thesis, two methods are applied to …

ADVANCED HIGH STRENGTH STEEL THROUGH PARAEQUILIBRIUM CARBON PARTITIONING AND AUSTENITE STABILIZATION
More than 30 vol. pct. retained austenite was obtained in quenched and partitioned (QP) 0.3C-4.0Mn steels subjected to dual stabilization heat treatments (DSHT). The temperature of the second quench in the DSHT process successfully played an essential role in the retained austenite contents at …

The effect of microalloying on the morphology of austenite during hot working.
… treatment variables on the recrystallization of austenite, the transformation of austenite and precipitation strengthening in C-Hn steel containing niobium, niobium plus vanadium, vanadium and vanadium plus nitrogen. The amounts of niobium and vanadium were varied across the stoichiometric ratio …

On the spheroidal graphite growth and the austenite solidification in ductile irons
<p>"Evolutions of austenite and nodular/spheroidal graphite particles during solidifications of ductile irons were experimentally investigated. Spheroidal graphite particle and austenite dendrite were found nucleated independently in liquid. Austenite dendrite engulfed the spheroidal graphite …
