Abstract EN
The modelling of an axisymmetric industrial quenched chromium steel bar AISI-SAE 8650H based on finite element method has been produced to investigate the impact of process history on metallurgical and material properties.
Mathematical modelling of 1-dimensional line (radius) element axisymmetric model has been adopted to predict temperature history and consequently the hardness of the quenched steel bar at any point (node).
The lowest hardness point (LHP) is determined.
In this paper hardness in specimen points was calculated by the conversion of calculated characteristic cooling time for phase transformation t8/5 to hardness.
The model can be employed as a guideline to design cooling approach to achieve desired microstructure and mechanical properties such as hardness.
The developed mathematical model is converted to a computer program.
This program can be used independently or incorporated into a temperature history calculator to continuously calculate and display temperature history of the industrial quenched steel bar and thereby calculate LHP.
The developed program from the mathematical model has been verified and validated by comparing its hardness results with commercial finite element software results.
