Dynamic recrystallization behavior covering a wide austenite grain size range in Nb and Nb–Ti microalloyed steels
TL;DR: In this article, the dynamic recrystallization (DRX) behavior of Nb and Nb-Ti microalloyed steels has been investigated, and it has been observed that decreasing the values of the Zener-Hollomon parameter and the initial grain size, promotes dynamic re-stallization.

Sung-Il Kim,Yeon-Chul Yoo +1 more
TL;DR: In this paper, the dynamic recrystallization of AISI 304 stainless steel was studied with torsion test in the temperature range of 900-1100°C and the strain rate range of 5.0×10 −2 −5.0 × s −1.

Modeling the Flow Behavior of a Medium Carbon Microalloyed Steel under Hot Working Conditions
TL;DR: In this article, the constitutive equations for the flow behavior of a commercial 0.34 pct C-1.5 pct Mn-0.7 pct Si 0.083 pct V 0.018 pct Ti microalloyed steel were determined.

Modelling of the dynamic recrystallization of austenite in low alloy and microalloyed steels
TL;DR: In this paper, the dynamic recrystallization of a selection of low alloy and micro-alloyed steels was studied and Avrami's equation was modelled based on the experimental determination of flow curves and their subsequent modelling, making it possible to calculate the recrystized fraction (X{sub d}) as a function of all the variables which intervene in hot deformation: temperature, strain rate, austenite grain size and the chemical composition of the steel.

A model for the competition of precipitation and recrystallization in deformed austenite
TL;DR: In this paper, a physically-based model was developed to describe the interaction of static recrystallization and strain-induced precipitation in microalloyed steel, where the precipitates were assumed to form, exclusively, on dislocations.
