Retained austenite is a spe-cific crystalline form of iron and steel. The dark-colored needles shown are tempered martensite crystals and the light-colored areas are retained austenite …

Oct 1, 2025 · One of the common characteristics of such microstructures is the presence of bainitic ferrite and/or martensite and retained austenite, the latter usually presenting a high …

A microstructure evolution of the thermomechanically processed 3Mn-1.5Al type steel and mechanical stability of retained austenite were investigated during interrupted tensile tests.

Nov 23, 2023 · Therefore, this study uniquely compared the stabilities of retained austenite in two-phase microstructures with bulk austenitic microstructures of the same composition, across …

Mar 11, 2019 · Upon cooling to room temperature, a portion of austenite can be retained in the microstructure depending on the temperature at which the transformation occurred. In an …

Sep 12, 2024 · We accomplished this by comparing the austenite (γ) stability in two distinct microstructures: a two-phase RA/martensite microstructure and a one-phase γ microstructure, …

Jun 10, 2025 · Retained Austenite (RA) is a metastable phase present in certain steel alloys, particularly those that have undergone specific heat treatment processes. It is a crucial …

May 30, 2025 · Retained austenite forms when austenite is not fully transformed into other phases during cooling. It is often found in high-strength steels and plays a crucial role in enhancing …

The microstructure during bearing operation experiences a decay in retained austenite, causing compressive internal stresses in the region of decomposition. Martensite decay is also …

Two carbide free bainitic (CFB) microstructures were designed with the 9260 alloy such that considerable differences in retained austenite content and morphology were achieved. These …
