F82H Steel: Martensitic Transformation Splitting Under Controlled Cooling

Six samples of the F82H reduced activation steel alloy were tested in a high-resolution dilatometer. The samples underwent heating to 1050°C and cooling at six controlled rates from 1.5 to 50 °C/min, with dilatometric curves and phase fraction models generated. The data was produced by S. A. Ferraris and appears to be associated with open-access research.

Use Cases

• Modeling phase transformation kinetics based on experimental dilatometric curves.
• Analyzing the splitting phenomenon of martensitic transformation at low cooling rates.
• Correlating heat treatment parameters with microstructural evolution in RAFM steels.
• Validating mathematical models for austenite-martensite phase fractions using derived temporal derivatives.

Strengths

• Experimental data is derived from six distinct cooling rate conditions (1.5, 2, 3, 5, 10, 50 °C/min).
• Analysis is complemented by high-resolution FEG-SEM images for metallographic examination.
• Heat treatment parameters are precisely defined (normalized at 1040°C for 38 minutes, tempered at 750°C for 60 minutes).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
