This study used X10CrAlSi24 (1.4762) sheet material, which is widespread in bending processes of the energy sector. During bending of X10CrAlSi24 (1.4762) sheet materials, cracking and tearing occur due to these materials' brittleness at room temperatures. To avoid this phenomenon, bending was carried out by applying normalization treatments at 800 degrees C, 850 degrees C, 900 degrees C and 950 degrees C. V-bending processes were performed at three different bending angles (30 degrees, 60 degrees, 90 degrees) and by a 4.5 mm punch tip radius. V-bending processes were carried out without leaving the punch on the material, and crushing of the punch on the sheet material sectional area was allowed. As a result of the bending processes, spring-go occurred in the 30 degrees and 60 degrees bending applications, whereas spring-back occurred in the 90 degrees bending applications. The formation mechanism of capillary cracks (depending on deformation) due to internal stress especially at low temperatures was introduced by the microstructural characterization of the specimens.
