The contribution describes metallographic analyses assessment of titanium materials - a commercial purity titanium (Grade 2) and Ti-15V-3Cr-3Sn-3Al titanium alloy - after asymmetric incremental sheet forming (AISF) processing. Microstructure pattern and deformation mechanism of the titanium materials are given by the content ratio of α and β phases that define formability of the resulting material. For the sake of description of the deformed parts from the view of mechanical properties, the microhardness measurements were performed on the samples taken from various zones of the resulting complex shape after the AISF processing. A distribution of deformation in dependence of the zone in the AISF part is similar for both experimental materials. A less pronounced microstructure refinement in the Ti-15-3-3-3 alloy is probably given by the springback occurrence in the case of this alloy.

Keywords: AISF, titanium alloys, sheet forming, microstructure, microhardness
