Retained austenite and tempered martensite embrittlement in medium carbon steels [PDF]

open access: yesMetallurgical Transactions A, 1983
Electron microscopy, diffraction and microanalysis, X-ray diffraction, and auger spectroscopy have been used to study quenched and quenched and tempered 0.3 pct carbon low alloy steels. Somein situ fracture studies were also carried out in a high voltage electron microscope.

On the thermodynamic stability of retained austenite in 4340 steel

open access: yes, 1997
The effect of retained austenite on the mechanical behavior of quenched and tempered steels depends on its thermodynamic stability against mechanically-induced martensitic transformation during loading.

A Comparative Study on the Dynamic Tensile Behavior of Nanostructured Bainitic and Quenched-Tempered Martensitic Steels

open access: yesMetals, 2018
In order to assess the dynamic tensile behavior of a newly developed three-step low-temperature-transformed bainitic microstructure, and a conventional one-step isothermal bainitic microstructure, and a quenched and tempered martensitic microstructure, a

INFLUENCE OF COOLING RATE ON THE OCORRENCE OF RETAINED AUSTENITE IN A STEEL FOR WELDING ELECTRODES [PDF]

open access: yesTecnologia em Metalurgia, Materiais e Mineração, 2015
The effect of cooling rate on the occurrence of retained austenite in a low carbon Si-Mn steel, used for welding electrodes, is measured here by combining the sectioning of Jominy test samples with the measurement of retained austenite by X-ray ...

Precipitation‐Modulated Harmonic Architectures Enable Superior Strength–Ductility Synergy from Cryogenic to Elevated Temperatures in Nanostructured Alloys

open access: yesAdvanced Science, EarlyView.
Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

Physics‐Informed Machine Learning for Sustainable Alloy Design: Toward a Recyclable Unified Q&P Steel

open access: yesAdvanced Science, EarlyView.
A physics‐informed property‐bridging framework links high‐throughput hardness screening to tensile performance in quenching and partitioning steels. By transferring metallurgically guided representations across properties, a single alloy composition is designed to achieve multiple strength grades through heat‐treatment tuning alone, offering a ...
