The role of the austenite grain size in the martensitic transformation in low carbon steels

open access: yesMaterials & Design, 2019
There is sufficient experimental evidence to propose that the formation kinetics of athermal martensite directly depends on the austenite grain structure from which the martensite forms. Yet, this dependence is frequently ignored.

EFFECTS OF TEMPERATURE ON AUSTENITIZING GRAIN SIZE STEEL 31CrMoV9

open access: yesЛитьë и металлургия, 2016
Austenitizing studied the effect of temperature on austenite grain size of the chrome-molybdenum-vanadium steel. It is shown that at austenitizing 850–1050ºS in the structure of chrome-molybdenum-vanadium steel nominal diameter of austenite grain varies ...

Effect of precipitates on the austenite grain growth of titanium microalloyed high performance steel

open access: yes工程科学学报, 2016
An austenite grain growth model was established by analyzing the quantificational relationship between precipitates and austenite grain size. The austenite grain size of Ti microalloyed steel with the interaction of TiN and TiC panicles was calculated by
