Abstract
The article is devoted to the fractographic study of double fracture surfaces during standard tensile tests of samples of ball-bearing steel developed by FSUE VIAM. Double destruction occurred simultaneously either in two fillets, or in the working part of the sample with the formation of a thin plate. Such an unexpected failure was never realized when testing structural alloys with ultimate strength characteristics. A hypothesis was put forward about possible destruction by the spallation mechanism, but the version of multiple destruction was not rejected either. The fractographic analysis of the surface of fractures with high reliability confirms the hypothesis of spall fracture.
