“Carburizing!” can be used to predict the distribution of carbon
in the carburized layers of steel and for the visual presentation
of the calculation results. Numerical methods have been utilized to determine
the distribution of carbon across a carburized layer.The program has been
written for the Microsoft Windows 95™ operating system.
This application can be an excellent teaching aid for a course of material
science for students majoring in mechanical engineering or material sciences.

2. How to get more information
For any given process of steel carburization, the program enables you
to monitor the effect of the following:
The program can also be used to optimize the steel carburization process.
This can be achieved by selecting appropriate parameter values which will
lead to the desired carbon concentrations throughout the diffusion layer.
the diffusing saturation time on the distribution of the diffusing element
across the diffusion layer, and on the kinetics of the layer build-up.
the surface reaction rate on the thickness of the diffusion layer, and
on an element’s concentration at the surface of the alloy.
the temperature on the rate of the diffusion layer’s growth
mass increase of the treated object as a function of the treatment
The following parameters are used as input for the calculations:
Both the data and the calculation results are displayed on the screen by
graphing the following parameters as a function of the treatment time:
the chemical composition of the steel subjected to carburization process
and the carbon transfer coefficient
the changes in temperature and in the carbon potential of the atmosphere
as a function of the treatment time
How to get more information
the temperature and the carbon potential of atmosphere
the carbon concentration on the steel surface
the thickness of the carburized layer up to the following concentrations
- 0.3%C, 0.35%C and 0.4%C,
both the carbon distribution and the hardness gradient across the carburized
