Description:
This dataset contains experimental data related to the study of hydrogen embrittlement in additively manufactured AISI 316L stainless steel.
The data correspond to the results presented in the associated conference paper (METAL 2026).

Abbreviations:
VS  – as-built condition (výchozí stav)  
VZS – annealed condition (výchozí žíhaný stav)

Directory structure:

Tensile tests.xlsx
Excel file with both processed and raw tensile test data.
- Processed data include yield strength, ultimate tensile strength (Rm), elongation (A), and hydrogen embrittlement index (F).
- Raw data (force–displacement / stress–strain) are provided in separate sheets for each specimen and condition.

Hardness
Contains six sheets corresponding to individual specimens.
- Each sheet includes Vickers hardness (HV1) measurements

Fracto_...
SEM images of fracture surfaces.
- Images represent both as-built (VS) and heat-treated (VZS) conditions.
- Both hydrogen-charged and uncharged specimens are included.

Microstructure_...
Photos from optical microscope of etched samples.
- Images show the microstructure in the as-built (VS) and heat-treated (VZS) conditions.

Experimental notes:
- Tensile tests were performed using slow strain rate testing (SSRT) with crosshead speed 0.5 mm/min (10⁻⁴10E-4 s⁻1).
- Hydrogen charging was carried out electrolytically in 0.05 M H₂SO₄ with KSCN addition.
- Heat treatment: 1050 °C / 30 min / 20 °C per minute / furnace cooling.
