In this paper the digital image analysis of voids formed during the deformation of steel samples in the GLEEBLEE 3800 physical simulator device with the semi-solid core. The presented and characterized indicators describe the shape of voids, and their relative position as qualifiers quality indicators as well as the correlation between the indicators and possible defects in the material. The paper contains the results and discussion of presented analysis.
