A numerical simulation of the Jominy end-quench test
- Weierstrass Inst. for Applied Analysis and Stochastics, Berlin (Germany)
The author presents a numerical algorithm for simulating the Jominy end-quench test and deriving continuous cooling diagrams. The underlying mathematical model for the austenite-pearlite phase transition is based on Scheil`s Additivity Rule and the Johnson-Mehl equation. For the formation of martensite the author compares the Koistinen-Marburger formula with a rate law, which takes into account the irreversibility of this process. He carries out numerical simulations for the plain carbon steels C 1080 and C 100 W 1. The results suggest that the austenite-pearlite phase change may be described decently by the Additivity Rule, except for the incubation time. On the other hand, using a rate law to describe the martensite formation is preferable to the Koistinen-Marburger formula, which leads to unphysical oscillations of the cooling curves in simulated CCT-diagrams.
