Air-Hardening Die-Forged Con-Rods—Achievable Mechanical Properties of Bainitic and Martensitic Concepts

open access: yesMetals, 2022
Three air-hardening forging steels are presented, concerning their microstructure and their mechanical properties. The materials have been produced industrially and achieve either bainitic or martensitic microstructures by air-cooling directly from the ...

Development of advanced cementite-free bainitic steel using Ni, Al and Cu additions – Design concept and phase transformations study

open access: yesJournal of Materials Research and Technology, 2023
A novel concept, consisting of the stabilization of retained austenite with Ni, Al, and Cu additions instead of using Si as the major alloying element to prevent carbide formation, is proposed to design nanocrystalline, cementite-free bainitic steels. In

Advanced Ultrahigh Strength Bainitic Steels [PDF]

open access: yesMaterials and Manufacturing Processes, 2007
The addition of about 2 wt.% of silicon to steel enables the production of a distinctive microstructure consisting of a mixture of bainitic ferrite, carbon-enriched retained austenite, and some martensite. With careful design, impressive combinations of strength and toughness have been reported for high-silicon bainitic steels.

Texture Evolution of Bainitic Steels Processed from Nickel Lateritic Ores: A Neutron-Diffraction Investigation [PDF]

open access: yesE3S Web of Conferences
This study investigated the texture evolution of bainitic steel samples processed from lateritic nickel ores with varying heat treatment times. The samples were austenitized, air-cooled, and subjected to bainitic heat treatment at 532°C for 15 and 30 ...

Enhanced Strength and Ductility by Introducing Nanobainitic Ferrite in Bainitic Steel Used in Sports Equipment

open access: yesMetals, 2021
The mechanical properties of carbide-free bainitic steels used in sports equipment were investigated. The nanobainitic ferrite was introduced in bainitic steel to enhance the stability of blocky retained austenite (RA).

Effect of Dislocation Density on Deformation Behavior of Super Strong Bainitic Steel

open access: yesJournal of Advanced Materials in Engineering, 2017
Presence of nanoscale bainitic ferrites and high carbon retained austenites that are stable at ambient temperature within the microstructures of super strong bainitic steels makes it possible to achieve exceptional strengths and ductility properties in ...

Transferring Nanoscale Bainite Concept to Lower C Contents: A Perspective

open access: yesMetals, 2017
The major strengthening mechanisms in bainitic steels arise from the bainitic ferrite plate thickness rather than the length, which primarily determines the mean free slip distance.
