This publication contains comprehensive metadata and test results of constant force creep tests according to DIN EN ISO 204 on the aluminum alloy EN AW-2618A in the T61 condition (8 h/530 °C/quenching in boiling water followed by 28 h/195 °C/air cooling) and in an overaged condition (T61 + 1.000 h/190 °C). The test temperatures cover 160 °C, 180 °C, 190 °C, and 230 °C, and the initial stresses range between 40 MPa and 290 MPa. The tests were carried out in an ISO 17025 accredited test laboratory. The investigated material and the applied methods are described in detail in [1-2]. All specimens tested came from the same batch of material. The data are provided using v1.1 of the “NFDI-MatWerk/IUC02 Data schema for creep data of Ni-based superalloys, including a comprehensive documentation of test results and metadata” [3] as a template for data documentation and structuring. The provided XLSX file, titled “2025-06_Data-Schema_Creep_v1.1_EN AW 2618_v1.0.xlsx”, includes a data schema (see worksheet “Data-Schema-Creep_v1.1”), along with additional worksheets named according to their respective test IDs. In each of these test-specific worksheets, column K contains the responses corresponding to the individual schema entries listed in column F. Some of these responses refer to other worksheets within the same XLSX file, which contain relevant metadata or test results. In addition, *.LIS files (in ASCII format) are provided. These files include a header section containing selected mandatory metadata and test results, followed by the required data series (time, creep strain/percentage creep extension). A PDF document includes the technical drawing of the test piece geometries. All numerical data on test results given in the XLSX file follow the decimal point conventions specified in DIN EN ISO 204:2019-4, aligned with the resolution of the measurement instruments used. The measurement uncertainties for test temperature (T), initial stress (R₀), and percentage extensions (e) were determined following CWA 15261-3:2005[4].
