Effect of Carbon Distribution During the Microstructure Evolution of Dual-Phase Steels Studied Using Cellular Automata, Genetic Algorithms, and Experimental Strategies

Determinação Das Temperaturas De Transformação Ar1 E Ar3 Em Barras De Aço Ca-50 Laminadas a Quente / Determination of the Transformation Temperatures Ar1 and Ar3 for Hot Rolled Ca-50 Steel Rebars

“…The steel rolling in at the inter critic field happens in a temperature which is situated between critic temperatures A1 and A3, there the steel will be conformed with its microstructure compound by Ferrite (α) and Austenite (γ). Normally this kind of rolling its applied on high resistance special steels, as in Dual Phase steels [6,7]. One factor that influences in the transformation speed is the heating or cooling rate.…”
