2. Description

This dataset accompanies the publication:

Direct observation of crack arrest after bridge notch failure: A strategy to increase statistics and reduce FIB-artifacts in micro-cantilever testing

Materials & Design, Volume 233, 2023, 112188

DOI: https://doi.org/10.1016/j.matdes.2023.112188

The dataset includes:

• Load-displacement data from each microcantilever (converted to accessible .txt format).

• Geometrical parameters of tested cantilevers (Excel file).

Cantilevers from two different materials were investigated:

1. Monoclinic CrN hard coatings

2. CrN/AlN multilayered hard coatings

⸻

3. Contents

• raw_data/ – Load–displacement data of each cantilever (converted from .hys to .txt).

• cantilever_geometry.xlsx – Summary of cantilever geometrical parameters.

• README.md – Documentation file.

⸻

4. Methodology

• Experimental setup:

Microcantilever bending tests performed with a Bruker Hysitron PI89 indenter equipped with a low-load transducer.

• Data recording:

Original raw files were stored in proprietary .hys format. For accessibility, all data were converted to plain-text .txt format.

• Tested materials:

• Monoclinic CrN

• CrN/AlN multilayer coatings

⸻

5. File Formats

• .txt – ASCII text files containing load–displacement curves.

• .xlsx – Microsoft Excel file summarizing geometrical parameters.

⸻

6. Usage Notes

• The .txt files can be opened with any text editor or processed with scientific software (e.g., Python, MATLAB, Origin).

• The Excel file provides cantilever dimensions, which should be considered for data interpretation.

• For proper context and interpretation, please refer to the associated publication.
