Abstract
In order to get rid of thermal interferences, the experiment was conducted to test the temperature drops of 40Cr by embedding thermocouple in central part of the steel specimen under the air cooling conditions. The cooling rate of the center was obtained and the phase transition temperature at the start and end points were determined. By comparing with 40Cr CCT curves, obvious effects of the metal phase transition latent heat on cooling rate were shown. The results should be revised when CCT curves which obtained form constant-speed cooling rate conditions were used to determined phase transition start and end temperature in non-constant cooling rate conditions.
