Nanobainite Generated in Low‐ and Medium‐Carbon Steels via an Economical Alloying Strategy [PDF]
A low‐cost strategy for generating fast transforming nanobainitic (nB) steels in low‐ and medium‐carbon alloys is investigated. Accelerating the bainite transformation relies on adding 0.7–3 wt% Al. Alloys and heat treatments are designed via thermodynamic calculations and dilatometry.

Effect of Nanobainite Content on the Dry Sliding Wear Behavior of an Al-Alloyed High Carbon Steel with Nanobainitic Microstructure. [PDF]
In this work, a multiphase microstructure consisting of nanobainte, martensite, undissolved spherical carbide, and retained blocky austenite has been prepared in an Al-alloyed high carbon steel. The effect of the amount of nanobainite on the dry sliding wear behavior of the steel is studied using a pin-on-disc tester with loads ranging from 25–75 N ...

On the crystallographic characteristics of nanobainitic steel [PDF]
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 ...

Glow discharge nitriding of nanobainitic X37CrMoV5-1 steel
Abstract One of the methods of improving mechanical properties of steels is nanostructuring via austempering, which leads to formation of a nanobainitic microstructure - a fine carbide-free bainitic ferrite plates with retained austenite. Due to high density of grain and interphase boundaries, this microstructure provides high tensile strength.

Tensile Ductility of Nanostructured Bainitic Steels: Influence of Retained Austenite Stability
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.
