Identification and range quantification of steel transformation products by transformation kinetics
- Oregon Graduate Inst. of Science and Technology, Beaverton, OR (United States). Dept. of Materials Science and Engineering
This study applied the generalized reaction rate equation to isothermal transformation kinetic data of a high-carbon low-alloy steel and a plain-carbon steel. As a result, a relationship between the curve shape constant n and transformation temperature emerged. Detailed analysis of this relationship yielded a correlation between austenite decomposition mode and transformation temperature. Using this correlation, it is possible to determine pearlite, upper bainite, and lower bainite transformation temperature ranges and to find the transition temperature region between any two reactions. This development led to a new microstructural characterization technique which identified transformation product through transformation kinetics with minimal metallographic analysis.
