Effect of reverted austenite on tensile and impact strength in a martensitic stainless steel−An in-situ X-ray diffraction study

Austenite reversion in low-carbon martensitic stainless steels – a CALPHAD-assisted review

“…Reverted austenite may also transform to martensite by strain-induced transformation and in this way enhances the plastic regime [45,71,72,81]. This mechanism known as transformation induced plasticity, has not been treated in depth in low-carbon martensitic stainless steels, but advanced in-situ experiments and modelling of strain-induced martensite formation have been performed in other variations of steels [82][83][84][85][86][87][88].…”

Martensite Formation from Reverted Austenite at Sub-zero Celsius Temperature

“…No further change in the phase fraction is measured on continuous cooling to room temperature for the samples treated to 898 K and 923 K; for cooling from 948 and 973 K reverted austenite partially transforms into martensite. In all cases inter-critical treatment yields a significant fraction of reverted austenite.It was demonstrated in Ref [19]. that the impact toughness of the present steel grade scales with the fraction of reverted austenite.…”

Solutions for Critical Raw Materials under Extreme Conditions: A Review

“…It is well known that not only the composition, but also the thermo-mechanical processing controls the sophisticated microstructures and, thus, the final properties of functionally-oriented materials. The Rietveld method in combination with the double-Voigt peak broadening model was used to analyze microstructural changes from X-ray diffractograms of stainless steels [ 114 ]. As the microstructural parameters (e.g., dislocation densities, phase fractions) are related to the mechanical properties, appropriate heat treatments for engineering steels to obtain tailored mechanical properties can be suggested by this approach.…”
