Retained austenite and tempered martensite embrittlement [PDF]
Metallurgical Transactions A, 1978 The problems of detecting the distribution of small amounts (5 pct or less) of retained austenite films around the martensite in quenched and tempered experimental medium carbon Fe/c/x steels are discussed and electron optical methods of analysis are emphasized. These retained austenite films if stable seem to be beneficial to fracture toughness.

Metals, 2021 Tempered martensite embrittlement (TME) is investigated in two medium carbon, high strength steels, 4340 (low silicon) and 300-M (high silicon), via rapid (1, 10, or 100 s) and conventional (3600 s) tempering. Rapid tempering of 4340 diminishes the depth

Microstructure-Properties Relationship and Mechanical Stability of Retained Austenite in Thermomechanically Processed Medium-C TRIP Steel at Different Deformation Temperatures [PDF]
Archives of Metallurgy and Materials, 2020 The paper presents the effect of deformation temperature on the mechanical stability of retained austenite in a multiphase TRIP steel. Series of static tensile tests were carried out in the temperature range –20 to 140°C in order to simulate the ...

Austenite formation from a steel microstructure containing martensite/austenite and bainite bands
Journal of Materials Research and Technology, 2023 In many commercial steel processing routes, steel microstructures are reverted to an austenitic condition prior to the final processing steps. Understanding the microstructure development during austenitization is crucial for improving the performance ...

Characterization of Retained Austenite in Advanced High-Strength Steel
Scanning, 2023 The retained austenite (RA) in advanced high-strength steels directly affects their plasticity. It is very important for the accurate characterization of their content and types. This paper prepared three specimens with three different Mn contents (1.0%, 1.4%, and 1.7%) that are used to obtain high-strength steel by ultrafast cooling heat treatment ...
