Austempering and Bainitic Transformation Kinetics of AISI 52100

open access: yesJournal of Materials Engineering and Performance, 2021
Abstract AISI 52100 is a high carbon alloy steel typically used in bearings. One hardening heat treatment method for AISI 52100 is austempering, in which the steel is heated to above austenitizing temperature, cooled to just above martensite starting (Ms) temperature in quench media (typically molten salt), held at that temperature until

Effect of Carbon Content on Bainite Transformation Kinetics and Microstructure of 4140/4150 Steels [PDF]

open access: yes, 2019
4140 steel and 4150 steel are different only in their carbon content. A comparison between the kinetics and microstructure of the bainite transformation of both steels has been carried out under a wide range of isothermal temperatures, in which four ...

Effect of Vanadium and Rare Earth on the Structure, Phase Transformation Kinetics and Mechanical Properties of Carbide-Free Bainitic Steel Containing Silicon

open access: yesApplied Sciences, 2022
Carbide-free bainitic (CFB) steels with a matrix of bainitic ferrite and thin layers of retained austenite, to reduce the manufacturing costs, usually do not contain alloying elements.

Effect of Ni addition on bainite microstructure of low-carbon special bar quality steels and its influence on CCT diagrams

open access: yesJournal of Materials Research and Technology, 2021
This work presents the effect of Ni content on the bainite morphology and in the mechanical properties of low-carbon special bar quality steels. Four steel ingots with the same base chemical composition, having only Ni content as their main difference ...
