title: BAM Reference Data: High Temperature Tensile Data of Single-Crystal Ni-Based Superalloy CMSX-6

description: This publication provides comprehensive metadata and test results of tensile tests at elevated temperature according to DIN EN ISO 6892-2:2018-09 on the single crystal Ni-based superalloy CMSX-6 at T = 980 °C. The tests were performed in an ISO 17025-accredited test laboratory. The calibrations of measuring equipment are documented, meet the requirements of the measurement standard, and are metrologically traceable. The provided data were audited and are BAM reference data. The preparation of this reference dataset adhered to the guidelines for the management of reference data described in [1]. Please consider citing this work [1] if you use the data for a scientific publication.

These data can be useful for verifying one’s own tensile test results on a nominally similar material, for verifying one’s own test setup (e.g., by testing the same or a similar material), and as input data for simulations of tensile or creep behavior in mechanical design or alloy development. There are currently no known restrictions on the use of the data.

The data are provided using v1.0 of the “NFDI-MatWerk/IUC02 Data schema for elevated temperature tensile data of Ni-based superalloys” [2] as a template for data documentation and structuring. The provided data fully meets the requirement profile (mandatory fields in the column “Requirement” of the data schema). The requirement profile was agreed between domain experts.

A XLSX file (“2025-12_HT-Tensile-reference-data-CMSX-6_v1.0.xlsx”), *.lis files (ASCII format), and supplementary images (PDF, JPG, TIF) are provided. The XLSX file contains metadata and selected test results that are valid for the entire test campaign (worksheet “Common-to-all”), as well as selected test results for the individual test pieces (worksheets named according to the respective test ID). The metadata and test results, i.e., the responses to the individual fields of the data schema [2], are provided in the last column, labeled as “Information”. Some responses refer to further worksheets in the same XLSX file. The *.lis files (ASCII format) contain a header with selected mandatory metadata and test results. Below the header, the mandatory data series are provided.

The decimal point setting is based on the specifications of DIN EN ISO 6892-1:2020-06 and DIN EN ISO 6892-2:2018-09 [3,4], and the resolution of the measuring devices. The total expanded uncertainty of measurement for tensile strength (Rm), proof strength (Rp0.2), and percentage reduction of area (Z) was determined according to DIN EN ISO 6892-1:2020-06 [3] for each test. The maximum values are given below in Table 1. The maximum temperature deviations observed were  -0.4 °C between the indicated, Ti, and the specified, T, temperatures, and 0.5°C (Ti) across the sample’s parallel length.
