## Contents
|
||||
|
||||
- **Thermal Images**:
|
||||
Time-series thermograms captured during high-temperature oxidation of AISI 1045 steel using an Optris PI 1M infrared camera.
|
||||
|
||||
- **Micrometer Data**:
|
||||
Thickness measurements acquired using a micrometer, reflecting total changes throughout the experiments.
|
||||
|
||||
- **Folder Structure**:
|
||||
- `Thermograms/`: Contains zipped folders for each experiment with thermal images in CSV.
|
||||
- `Micrometer/`: Contains xlsx files with thickness measurements that match thermal image timestamps.
|
||||
|
||||
Across all experiments, a total of 3386 synchronized thermal frames and thickness measurements were collected.
|

## Methodology
|
||||
|
||||
Steel specimens were subjected to Joule-heating experiments under controlled conditions. Thermal images were recorded. Micrometer readings were taken periodically during heating and cooling stages.
|
||||
The goal was to train machine learning regressors capable of estimating specimen thickness variations purely from thermal imaging data.
|
||||
Each experiment yielded approximately 700 paired measurements of temperature fields and corresponding specimen thickness values. This dense temporal sampling enabled precise tracking of thickness evolution throughout the oxidation process.
