Austenite grain growth and effect of austenite grain size on bainitic transformation
Materials Science and Technology, 2022This 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, 2023A 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.

Prediction of austenite grain growth during austenitization of low alloy steels
Materials & Design, 2008Although 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 in structural steel
Metal Science and Heat Treatment, 19721. The first period of austenite grain growth in steel 12Kh2N4A at 900\dgC (holding for 2 h or longer) is characterized by the formation of very large grains (grade 2\2-3) among fine grains (grade 9\2-10). The large grains are formed by the coalescence of fine grains into a single grain. 2. At higher temperatures there is less difference

Grain growth in austenitic stainless steels
Metallography, 1969Abstract Despite the extensive use of Type 347 stainless-steel tubing for regeneratively cooled thrust chambers, very little is known about its grain growth characteristics. Lacking, also, is information on the other 18 Cr8 Ni austenitic steels. Therefore, grain growth curves for AISI Type 304, 316, and 321 were obtained and compared.

Role of annealing twins in austenite grain growth
Metal Science and Heat Treatment, 19781. The change in the structure of the boundaries of recrystallized austenite grains during heating and the development of breaks in the boundaries are due to annealing twins growing from the breaks in the boundaries or near them. 2. Large numbers of annealing twins not connected with the boundaries of the matrix are observed in large ...
