Prediction of austenite grain growth during austenitization of low alloy steels

Materials & Design, 2008
Although the prior austenite grain size (AGS) of heat treatable low alloy steels is an influential factor in phase transformations during quenching and in mechanical properties, there are few equations to predict the AGS considering alloying element effects.

Austenite grain growth and effect of austenite grain size on bainitic transformation

Materials Science and Technology, 2022
This study was carried out with medium carbon steel to investigate the austenite grain growth kinetics at three temperatures and the effect of prior austenite grain size on bainitic transformation kinetics. Grain growth behaviour of austenite with two initial microstructures, pearlite and bainite, have shown almost similar kinetics.

Simulation of Austenite Grain Growth in Low-Alloyed Steels upon Austenitization

Physics of Metals and Metallography, 2023
A model has been developed that describes the grain growth upon austenitization, taking intoaccount the pinning of moving grain boundaries by carbonitride precipitates. The behavior of these precipitates is described using our previously developed approach for predicting the evolution of carbonitride particles.

Strengthening austenitic steels by using nanotwinned austenitic grains

Scripta Materialia, 2012
Abstract A novel strategy for strengthening austenite steels is introduced by using the unique strengthening effect of nanoscale twins. Austenite grains containing multiple nanoscale twins can be strengthened to a yield strength of a few GPa with very high work-hardening rates.

Tensile ductility of nanotwinned austenitic grains in an austenitic steel

Scripta Materialia, 2014
Dynamic plastic deformation followed by recovery annealing of an austenitic stainless steel results in the formation of a hierarchical microstructure consisting of nanotwinned austenitic grains (>55 vol.%) mixed with nanograins and dislocation structures.
