Refractory high entropy alloy dataset with room temperature ductility screening

This dataset contains 82 unique refractory alloys experimen-tally synthesized via arc melting and subject to screening tests for hardness and room temperature ductility. Most com-positions fall under the definition of high entropy or com-plex concentrated alloys, but simpler ternary compositions are also included. Hardness was collected via a standard in-dentation technique while compressive ductility was quanti-fied using a custom high throughput experimental approach yielding a ductility ranking from 0 to 5. The unique ductil-ity screening test was developed to provide directional infor-mation for alloy development at a low cost and rapid pace using conventional test equipment. Predicted solidus temper-ature for all alloys is also included based on thermodynamic modelling. The dataset should be of interest to those explor-ing the emerging class of refractory high entropy alloys and particularly useful where optimization is sought balancing strength, ductility, and high melting temperature.
