Modeling the austenite-ferrite transformation in microalloyed steel P510L

Abstract

Based on experimental results, the transformation kinetics and cooling characteristics of low-carbon steel were analyzed and modeled to quantitatively link the operational parameters of a process with the properties. From the continuous cooling transformation results, comparisons of the start temperature of austenite-ferrite transformation among three models were analyzed, and the optimal lnk and n, which are the parameters in the Avrami equation, were determined by applying two regression models at different cooling rates. The transformation kinetics during continuous cooling was determined. Furthermore, reasonable agreements between experimental results and predictions were obtained, which can demonstrate the rationality of the established models.

A novel diffusion model considering curvature radius at the bonding interface in a titanium/steel explosive clad plate

“…Li et al [17] performed a numerical simulation of macro-segregation in steel ingots using a two-phase model. Yu et al [18] modeled the austenite-ferrite transformation in microalloyed steel P510L. Han et al [19] investigated the interface of Cu/Al couples during an isothermal heating process.…”

“…Han et al [19] investigated the interface of Cu/Al couples during an isothermal heating process. Notably, most of these previous works [14][15][16][17][18][19][20][21][22] have been focused on the diffusion model of a straight interface of clad plates, whereas little attention has been devoted to the curved interface of the clad plates.…”
