Jominy Predictor

Predict Jominy hardenability curves and microstructural response for steel alloys.

Generate Accurate Jominy Hardenability Curves with DANTE Models

Jominy Predictor simulates hardness and microstructural profiles along a Jominy end-quench bar using DANTE’s metallurgical material models. By incorporating alloy chemistry, carbon distribution, and transformation kinetics, this tool delivers reliable predictions for evaluating hardenability and cooling response.

Advanced Hardenability Simulation Using the Jominy End-Quench Test

Jominy Predictor is a specialized material characterization tool designed to generate Jominy hardenability curves for steel alloys. Leveraging the DANTE material database and transformation kinetics models, it predicts how hardness and phase fractions evolve along the length of a simulated Jominy bar under end-quench conditions.

This tool is essential for metallurgists, process engineers, and researchers who need to evaluate steel hardenability, compare alloy grades, validate supplier specifications, or support heat-treat process design.
