## What is HeatTreat Studio?

HeatTreat Studio is an on-device engineering screening workspace for process engineers, manufacturing teams, and materials learners. It brings materials, thermal programs, boundary conditions, numerical diagnostics, and plant-data calibration into one mobile workflow.

HEAT-TREATMENT SIMULATION
• 1D slab, long-cylinder, and sphere geometries
• Multi-stage ramps, holds, air transfers, staged quenching, and tempering
• Furnace convection/radiation and temperature-zone quench boundaries
• Thermal fields, surface/core histories, phase fractions, and hardness trends
• 51/101/201-node and half-time-step diagnostics
• Constant-property analytical-series benchmarks and numerical-confidence guidance

MATERIALS AND SCENARIOS
• Engineering-seed packs for 45, 40Cr, and 42CrMo steels
• Transparent source, capability, maturity, and applicability information
• Overlay comparison for up to four scenarios
• Jominy, CCT/TTT, and tempering tools activate only when the selected pack provides the required data—no silent cross-grade defaults

PLANT-DATA CALIBRATION
• Import thermocouple, HRC, and Jominy CSV files
• Map sensor positions, units, batches, and measurement uncertainty
• Fit zone heat-transfer multipliers, transfer-time offset, and one hardness-mapping multiplier
• Compare baseline and calibrated errors, identifiability, approximate intervals, and holdout results
• Immutable calibration revisions with factory-profile snapshots
• Password-encrypted .htpack private packages

PROJECTS AND REVIEW
• Save reproducible local .htproject files
• Export Markdown, PDF, and CSV review packages
• Core calculations and private-data processing stay on device

This app supports engineering screening, learning, and calibration assistance. It does not issue acceptance decisions, process certification, or production guarantees. Bundled public materials are engineering seeds, not a substitute for licensed databases, plant trials, equipment qualification, or professional review. Validate with your own material batch, equipment, and measurements before production use.
