Abstract Scope Understanding the relationship between microstructure features and mechanical properties is of great significance for the improvement and specific adjustment of metal sheet properties. Hole expansion capacity plays an important role in defining the formability of metal sheets. Due to the complexity of the experimental procedure of testing hole expansion capacity, where many influencing factors contribute to the resulting values, the relationship between microstructure features and hole expansion capacity is not clearly studied. In the present study, an experimental data set containing the phase constituents of the microstructure as well as corresponding properties, such as hole expansion capacity, yield strength and bendability, is collected from literature. Systematic mathematical analysis on these data is conducted with the focus on hole expansion capacity based on individual phases, combinations of phases and number of phases. In further study, machine learning will be applied to reveal more information.
