Geometry of dimples and its correlation with mechanical properties in high-strength bainitic steel

ABSTRACT

The experimental measurements of $\mathit{2}\mathit{D}$ micro/nanolayered dimples' dimensions (both geometry and pattern) on the published tensile fractographs of a series of austempered high-strength low-carbon bainitic steel are carried out and interpreted with the corresponding initial microstructural features and tensile mechanical responses as a function of austempering temperature.
