Supplementary data on microcantilever fatigue tests
<p>This data publication contains the results of microcantilever fatigue tests on a metallic glass and tungsten. It supplements the publication “A new method for microscale cyclic crack growth characterization from notched microcantilevers and application to single crystalline tungsten and a metallic glass” DOI: <a href="http://dx.doi.org/10.1557/s43578-022-00618-x">10.1557/s43578-022-00618-x</a>. During the experiments four Zr<sub>48</sub>Cu<sub>36</sub>Ag<sub>8</sub>Al<sub>8</sub> metallic glass microcantilevers and five tungsten single crystal microcantilevers were tested. The compositions, orientations and the production of the microcantilevers are described in the publication.</p> <p>The fatigue tests were performed by S. Gabel under the supervision of B. Merle at the Institute I - General Materials Properties of the Friedrich-Alexander Universität Erlangen-Nürnberg <a href="http://www.ww1.tf.fau.de/">(<em>Martensstr.5, 91058 Erlangen, Germany</em>)</a> using a NMT 03 in-situ nanoindenter <a href="https://www.femtotools.com/">(<em>FemtoTools, Switzerland</em>)</a> inside a 1540EsB Secondary Electron Microscope <a href="https://www.zeiss.com/corporate/int/home.html">(<em>Carl Zeiss, Germany</em>)</a>. The indenter was equipped with a wedge diamond tip, which had a length of ~10 µm. The experiments were performed, until the tip lost contact with the microcantilever due to bending.</p> <p>The data for the fatigue tests are provided in nine <strong>.csv</strong> files, each corresponding to a single test and being divided into two folders, sorted by the material. The numbers in the files names describe the initial cyclic stress intensity factor <em><strong>ΔK<sub>I</sub></strong></em>. This is also used in the publication to describe the single tests. The data in each <strong>.csv</strong> file are organized as follows:</p> <p>Each row contains thirteen semicolon separated characters, forming thirteen columns. The data description are given in row 1, e.g., "Stiffness". The physical unit is given in row 2, e.g., "N/m". From row 3 on the data for the individual experiment are given. The following information can be found in the respective columns:</p> <p>1: Cycle number. 2: Mean force <strong><em>P<sub>m</sub></em></strong> in µN. 3: Force amplitude <em><strong>ΔP/2</strong></em> in µN. 4: Displacement amplitude <em><strong>Δh/2</strong></em> in µm. 5: Stiffness <em><strong>S<sub>CSM </sub></strong></em>in N/m. 6: Crack growth length <em><strong>Δa</strong></em> in µm. 7: Stress intensity factor range <em><strong>ΔK<sub>I</sub></strong></em> in MPa√m. 8: Initial crack length <em><strong>a</strong></em> in µm. 9: Cantilever width <em><strong>W</strong></em> in µm. 10: Cantilever thickness <em><strong>T</strong></em> in µm. 11: Span length <em><strong>L</strong></em> in µm. 12: Phase shift in °. 13: Temperature in °C.</p> <p> </p> <p>One test with metallic glass was performed with a higher recording rate of 400 Hz, which can be found in the folder: <em>"Metallic_Glass_High_Recording_Rate"</em>. The data in the <strong>.csv</strong> file are sorted differently to the other tests:</p> <p>Each row contains fifteen semicolon separated characters, forming fifteen columns The data description is given in row 1, e.g., "Stiffness". The physical unit is given in row 2, e.g., "N/m". From row 3 on the data for the individual experiment are given. The following information can be found in the respective columns:</p> <p>1: Time in s. 2: Cycle number. 3: Mean displacement <em><strong>h<sub>m</sub></strong></em> in µm. 4: Mean force <strong><em>P<sub>m</sub></em></strong> in µN. 5: Force amplitude <em><strong>ΔP/2</strong></em> in µN. 6: Displacement amplitude <em><strong>Δh/2</strong></em> in µm. 7: The force <em><strong>P</strong></em> in µN. 8: Displacement <em><strong>h</strong></em> in µm. 9: Stiffness <em><strong>S<sub>CSM </sub></strong></em>in N/m. 10: Initial crack length <em><strong>a</strong></em> in µm. 11: Cantilever width <em><strong>W</strong></em> in µm. 12: Cantilever thickness <em><strong>T</strong></em> in µm. 13: Span length <em><strong>L</strong></em> in µm. 14: Phase shift in °. 15: Temperature in °C.</p>
