IN625 Tensile Test Data at Multiple Strain Rates

Macro-scale tensile data from five experiments on additively manufactured IN625 specimens. The data includes time, engineering strain, and engineering stress measurements from tests at two different strain rates. The dataset was produced by the National Institute of Standards and Technology in 2022.

Use Cases

• Model stress-strain curves for IN625 using engineering stress and engineering strain data from five experiments.
• Analyze the effect of strain rate on material properties by comparing results from the 0.001 1/s and 0.01 1/s test groups.
• Validate finite element models of tensile behavior against the time-series data from servo-hydraulic machine tests.
• Benchmark predictive models for fracture strain using the reported virtual extensometer strain data up to fracture.

Strengths

• Data from five distinct tensile experiments provides multiple data points for analysis.
• Includes tests at two specific strain rates (0.001 1/s and 0.01 1/s) for comparative study.
• Detailed accompanying PDF document describes additive manufacturing procedures and material composition.
• Measurements follow the ASTM-E8 standard for subsize specimen geometry.

Limitations

• Small sample size with only five total specimens, limiting statistical power.
• Limited to two strain rates and a single material (IN625) in the as-built condition.
• No columnar metadata or row count is provided for the CSV files, requiring inspection.
