Jominy end quench test is a standard test used to characterize hardenability of steels. There
are some theories focused on correlation between cooling curves and hardness of the test
specimen such as quench factor analysis (QFA). In this research it was tried to simulate
the Jominy test of a steel (AISI 4130) with the method. By considering the phase transformation
during quenching and material properties, cooling curves of different points were
determined. Then, using time–temperature-properties (TTP) curve of 4130 steel, function
constants of the curve (CT) were obtained. Finally, the QFA was derived using the simulated
results and maximum and minimum hardness of the steel. The extracted results from QFA
are hardness of different points of Jominy specimens. The data obtained from QFA were
compared with the experimental results. The comparison showed a good agreement at the
low specification but not at the high specification successfully.
