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.

Austenitic grain size of hydroextruded high-speed steels
Metal Science and Heat Treatment, 19811. To obtain a fine and uniform austenitic grain size in hardening of hydroextruded steels, a post-deformation temper at 500°C is recommended. After hydroextrusion with large degrees of deformation (">30%), heating to temperatures close to the Ac1 point (750°C) with short holds (5–10 min) may be used. 2.

Martensite start temperature and the austenite grain-size
Journal of Materials Science, 2010The dependence of the martensite start temperature on the austenite grain-size is modeled based upon aspects of martensite nucleation and validated by data reported in the literature. The results obtained support the view that grain boundaries provide an environment for the formation of martensite embryos in annealed austenite.

Austenite grain size and the martensite-start temperature
Scripta Materialia, 2009New experimental evidence confirms the dependence of the martensite-start temperature on the austenite grain size. The Fisher model for the geometrical partitioning of austenite grains by plates of martensite is used here to develop a theory to explain the observations, based on the ability to detect transformation as a function of the austenite grain ...

Modeling the Effect of Austenite Grain Size Distribution on Austenite Decomposition Kinetics
Materials Science Forum, 2007The model of the γ→α transformation calculated with the CATRAN program is described. The expected effect of former austenite grain size on the transformation kinetics as well as the final microstructure is analyzed and compared with experimental data.
