摘要

Heat treaters need an effective simulation tool to predict the carburization performance of a variety of steels. The tool is needed to not only predict the carbon profile but also optimize the process in terms of the cycle time and the total cost. CarbTool has been developed to meet these needs for gas and vacuum carburization. In this article, CarbTool predictions were compared with industrial experimental results for three types of steels (AISI 8620, 5120, and 4320), heat treated by both gas and vacuum carburizing processes. Based on the agreement of model predictions and experimental results, it is found that CarbTool could be used to predict the carbon concentration profile for a variety of alloys in both gas and vacuum carburizing processes.
