DANTE

Through DANTE modeling, the blackbox of heat treatment becomes illuminated on a component-specific level by capturing the in-process evolution of microstructural phase transformations, hardness, distortion, and residual stress through our state-of-the-art materials model. This advantage of process modeling helps to provide a deeper insight into the outcomes of heat treat operations.

Those who have heard of Dante know the challenges of heat treatment engineering. Here at Dante, our goal is to help solve those challenges by illuminating the black box that is heat treatment. To solve those problems, we offer a variety of products as well as consulting services.

What's New

				
					Dante 6_2a
2/7/2025
- Carburizing model: alloy precipitates (carbides) use actual size (nm) instead of normalized size. The effect of carbide size on carbide decomposition rate is improved.
- Alloy precipitates use actual volume fraction instead of carbon equivalent weight fraction.
- Added a contribution of carbide fraction on individual phase hardness and carbide direct contribution on hardness.
- TRIP parameter update allows for definition of retained austenite below room temperature.
- Effect of carbide volume fraction on carbon diffusivity is updated.
- Implemented martensitic transformation kinetics for diffusive phase effect on further martensitic transformation.
- System variable “DANTE_PATH” is retired. “DANTE_PATH_DIR” is used for future versions.
