2DELTA: Cooling Diagram


Cooling diagrams apply only to processes with cooling stages.

This diagram shows temperature dynamics at selected part points during the process of cooling. cool2In 2DELTA, all cooling curves start at the time when the local temperature crosses a line of the designated temperature specified by the user. It means that zero point of the time scale is individual for each element of the cross-section.
The Ar temperature may be used as a characteristic temperature for heat treating processes. This graph may be displayed in normal or logarithmic scales.
Applying the Time-Temperature Transformation curves (thermodynamics,  kinetics ZTU-diagram or other types of diagram) to this graph, the user can find the structural transformations in the part cross-section including the case depth and hardness.

This diagram can predict the quality of hardening process that depends on the quality of cooling media and other parameters.
