In this work, the fracture surface of a 1.0481 steel sample having a layered ferrite-martensitic structure after special heat treatment was studied by optical and scanning electron microscopy. The samples were subjected to a shock-bending test at negative temperature. A sample made of the same steel with a homogeneous martensitic structure was used for comparative analysis. The features of the destruction mechanisms of the studied samples are described.
