## Numerical study of quenching heat treatment: Influence of the cooling modes on the hardness

 AUTHOR(S): Mohamed Chaour, Khedidja Bouhamla, Mounira Bourebia, Sofiane Bolkroune TITLE Numerical study of quenching heat treatment: Influence of the cooling modes on the hardness PDF ABSTRACT This paper is part of a research project aimed at improving the mechanical properties and microstructural of the grinding ball. In this study, we are interested in the numerical analysis by the finite difference method of quenching to examine the influence of quenching media on cooling rate and hardness. The numerical calculation was carried out using the FORTRAN language. The study is carried out on two alloy steels C32 and C70, simulating cooling curves from TTT diagrams. The results obtained for different cooling modes show that the material structure, the cooling rate and the hardness depend on the cooling medium KEYWORDS Numerical analysis, finite difference, quenching media, alloy steels REFERENCES [1] H.
