Tempering stability of retained austenite in nanostructured dual phase steels [PDF]

open access: yesMaterials Science and Technology, 2013
The tempering resistance and stability of retained austenite in superbainitic and quenching–partitioning martensitic steels were investigated over the temperature range of 400 to 700°C. The X-ray diffraction analysis and hardness tests showed that the quenching–partitioning martensitic steel contained a considerable amount of retained austenite (26·6 ...

Stability of retained austenite in martensitic high carbon steels. Part II: Mechanical stability [PDF]

open access: yesMaterials Science and Engineering: A, 2018
The mechanical stability of retained austenite is explored in martensitic bearing steels under cyclic compressive stresses up to ∼106 cycles at 3GPa, combining X-ray diffraction and repetitive push testing. Finite element analysis and hardness testing were adopted to interpret the stress distribution across the specimen, and the stress-strain response ...

Addressing Retained Austenite Stability in Advanced High Strength Steels

open access: yesMaterials Science Forum, 2013
Advances in the development of new high strength steels have resulted in microstructures containing significant volume fractions of retained austenite. The transformation of retained austenite to martensite upon straining contributes towards improving the ductility.

Stability of retained austenite in martensitic high carbon steels. Part I: Thermal stability [PDF]

open access: yesMaterials Science and Engineering: A, 2018
Thermal stability of retained austenite in 1C-1.5Cr steels with two Si and Mn contents is studied. Time-resolved high resolution synchrotron X-ray radiation and dilatometry are employed. The threshold transformation temperatures, decomposition kinetics, associated transformation strain, as well as the influence of Si and Mn were investigated.
