Effect of High Ti Contents on Austenite Microstructural Evolution During Hot Deformation in Low Carbon Nb Microalloyed Steels

open access: yesMetals, 2020
This work has focused on the study of hot working behavior of Ti-Nb microalloyed steels with high Ti contents (> 0.05%). The role of Nb during the hot deformation of low carbon steels is well known: it mainly retards austenite recrystallization ...

Microalloyed steels [PDF]

open access: yesIronmaking & Steelmaking, 2016
This review considers the compositions, the main process routes, microstructure, and structural properties of microalloyed steels. The background and brief history are followed by sections dealing with aspects of precipitation which control grain size and dispersion strengthening in ferrite- pearlite steels, the approaches to modelling thermomechanical

Flow Stress Behaviour and Static Recrystallization Characteristics of Hot Deformed Austenite in Microalloyed Medium-Carbon Bainitic Steels

open access: yesMetals, 2021
In the past decade, efforts have been focused on developing very fine, medium-carbon bainitic steels via the low-temperature (typically 300–400 °C) ausforming process, which not only enables shorter isothermal holding times for bainitic transformation at
