# Creep reference data of single-crystal Ni-based superalloy CMSX-6

## TL;DR

This paper provides detailed creep data for the CMSX-6 nickel-based superalloy, tested under various stresses and temperatures.

## Contribution

The study offers a standardized dataset of creep behavior for CMSX-6, supporting material validation and model calibration.

## Key findings

- Creep data was collected for CMSX-6 at 980 °C with stresses from 140 MPa to 230 MPa.
- The dataset includes 12 data series with percentage creep extension over time.
- The data is documented using a schema tailored for single-crystal Ni-based superalloys.

## Abstract

The article presents creep data for the single-crystal, [001]-oriented nickel-based superalloy CMSX-6, tested at a temperature of 980 °C under initial stresses ranging from 140 MPa to 230 MPa. The constant-load creep experiments were performed in accordance with DIN EN ISO 204:2019–4 standard within an ISO 17025 accredited laboratory. A total of 12 datasets are included, each of which includes the percentage creep extension as a function of time. The data series and associated metadata were systematically documented using a data schema specifically developed for creep data of single-crystal Ni-based superalloys. This dataset serves multiple purposes: it can be used to compare with one's own creep test results on similar materials, to verify testing setups (e.g., by replicating tests on the same or comparable materials), to calibrate and validate creep models, and to support alloy development efforts.
