The Microstructure and Properties of Carbon Thin Films on Nanobainitic Steel [PDF]
Metallurgical and Materials Transactions A, 2021 Abstract The aim of this study was to assess whether it is possible to produce a high adhesive carbon coating by applying low-temperature RFCVD and glow discharge methods on nanobainitic X37CrMoV5-1 steel with and without nitrided sublayer.

On the crystallographic characteristics of nanobainitic steel [PDF]
Acta Materialia, 2017 Abstract This study aims to elucidate the crystallographic characteristics of bainite transformed in a temperature range of 200–350 °C, where a nanobainitic structure is formed. The microstructure, consisting of bainitic ferrite laths and retained austenite, became significantly refined and its crystallographic arrangement changed with a decrease in ...

Microstructural and Mechanical Characterization of a Nanostructured Bainitic Cast Steel
Metals, 2020 Nanoscale bainite is a remarkable microstructure that exhibits a very promising combination of high strength with good ductility and toughness. The development of these types of microstructures has been focused on wrought materials, and very little ...

Modeling And Characterization Of High Carbon Nanobainitic Steels [PDF]
, 2021 Analytical models have been developed for the transformation kinetics, microstructure analysis and the mechanical properties in bainitic steels. Three models are proposed for the bainitic transformation based on the chemical composition and the heat treatment conditions of the steel as inputs: (1) thermodynamic model on kinetics of bainite ...

Tensile Ductility of Nanostructured Bainitic Steels: Influence of Retained Austenite Stability
Metals, 2017 High silicon (>1.5%) steels with different compositions were isothermally transformed to bainite at 220 and 250 °C to produce what is often referred to as nanostructured bainite.
