Abstract
In this paper, the temperature field of nodular cast iron in laser transformation hardening was simulated by using ANSYS software and tested with CCD-based colorimetric temperature measurement method. Firstly, the temperature field was calculated, and the width of the hardened track was estimated according to the calculated result. Then, the temperature field was measured in the presented experiments. After comparison of the calculated results to the experimental ones, it was found that the width of the hardened track can be predicted by the measured temperature field, which would help analyse the effect of process parameters and carry out real-time control in laser transformation hardening process.
