Characteristics of Retained Austenite in Cast GX70CrMnSiNiMo2 Alloy Tool Steel [PDF]
Archives of Foundry EngineeringMaterial wear strictly depends on hardness and microstructure, homogeneity of this microstructure in particular. The presence of retained austenite in the microstructure is not always the cause of the reduced wear resistance, though it is commonly ...

Study on the stability of retained austenite in marine steel [PDF]
Metalurgija, 2020 The residual austenite stability in marine steel was studied by different heat treatment processes. After heat-treatment process 1 (quenching + tempering) and heat treatment process 2 (quenching + intercritical annealing + tempering), the austenite ...

Theory and significance of retained austenite in steels [PDF]
, 2019 The processes 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 separate reactions, although both involve a ...

A theoretical review of the operation of vibratory stress relief with particular reference to the stabilization of large-scale fabrications [PDF]
, 2011 Vibratory stress relief (VSR) is widely used on large welded fabrications to stabilize the structures so that they do not distort during further machining or during operational duty.

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.

Characterisation and Development of Nanostructured, Ultrahigh Strength, and Ductile Bainitic Steels [PDF]
, 2006 The purpose of the present work was to characterise and further develop a novel nanostructured type of bainitic steel. Three chemical compositions were considered with different concentrations of Al and Co.

Effect of small addition of Cr on stability of retained austenite in high carbon steel [PDF]
, 2017 High carbon steels with dual phase structure of martensite and metastable austenite are strong, hard and cost effective. This makes them suitable for a number of industrial applications in high abrasive environments.

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
