Effect of prior martensite on the thermal stability of nanobainitic steels

Materials Research Express, 2019
Two types of the nanobainitic microstructures which consist of plate-like bainitic ferrite, retained austenite with and without martensite were obtained by quenching to Ms-12 °C and ausforming by about 30% before isothermal bainitic transformation at 300 °C.

Low-Alloyed Spring Steel: Nanostructure and Strength After Austempering

Metals
Carbide-free bainite microstructures were developed in 0.6 wt.%–2 wt.% Si spring steel via austempering at 250 °C. Heat treatment included austenization with subsequent isothermal holding at 250 °C, varying the holding duration to 1.0, 1.5, or 2.0 h with

Nanobainite formation in high-Al medium-Mn steels: thermodynamic approach

Journal of Thermal Analysis and Calorimetry
AbstractThe objective of this study was to analyze the thermodynamic feasibility of forming nanobainite in Al-alloyed medium-Mn steels through intercritical annealing (IA) and subsequent heat treatments. The research aimed to determine the influence of IA temperature and Mn content on the stability of austenite, the Ms temperature, and the resulting ...
