Laboratory- and Semi-Industrial-Scale Thermomechanical Processing of TRIP-Aided Steel with Acicular Ferrite

open access: yesApplied Sciences, 2021
The modification of the deformation and cooling methods resulting in the obtainment of acicular ferrite promotes an increase in the proportion of retained austenite (RA) and a corresponding increase in mechanical properties in Si-Al TRIP-aided steel. The

Deconstructing the Retained Austenite Stability: A Comparative Study of Two-Phase and Bulk Microstructures

open access: yes, 2023
The stability of retained austenite is a key factor in the design of advanced high-strength steels that exhibit excellent mechanical performance, including high strength and high ductility/toughness.

Effect of two-step ausforming on bainite transformation and retained austenite in a medium-carbon bainitic steel

open access: yesMaterials Research Express, 2020
It is commonly accepted that single ausforming with small strain at low temperature promotes isothermal bainite transformation and leads to more retained austenite.

Comparative study on effects of annealing temperature on microstructures and mechanical properties of high-Al low-Si steel

open access: yesJournal of Materials Research and Technology, 2023
We elucidate here profound effects of quenching and partitioning process after partial (IQP) or full austenitization (FQP) on the microstructure and mechanical properties of high strength hot-dip galvanized steel with high Al and low Si content.

The Influence of Tempering Temperature on Retained Austenite and Ductility–Toughness of a High-Strength Low-Carbon Alloyed Steel

open access: yesCrystals, 2023
High-strength alloyed steel has been widely used in engineering equipment because of its exceptional strength and toughness, particularly at low temperatures.

A theoretical review of the operation of vibratory stress relief with particular reference to the stabilization of large-scale fabrications

open access: yes, 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.

CRYSTALLOGRAPHY OF ""LATH MARTENSITE"" AND STABILIZATION OF RETAINED AUSTENITE [PDF]

open access: yes, 1982
TEM was used to study the morphology and crystallography of lath martensite in low and medium carbon steels in the as-quenched and 200/sup 0/C tempered conditions. The steels have microduplex structures of dislocated lath martensite and continuous thin films of retained austenite at the lath interfaces.

Characterisation and Development of Nanostructured, Ultrahigh Strength, and Ductile Bainitic Steels

open access: yes, 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

open access: yes, 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.
