“…This allows radial forging to be considered as a method of obtaining the non-uniform rod in its cross-section (quasi-composite material), along with well known methods of formation of non-heterogeneous gradient materials such as torsional deformation [12] and surface mechanical attrition treatment [13]. This fact has a positive effect on the resistance to the transverse crack impeding during the impact strength testing of the received CRF one-phase material [43].…”

The article presents the influence of structure formation on the properties of 321 metastable austenitic stainless steel in the process of cold radial forging (CRF). The steel under study after austenitization was subjected to CRF at room temperature with degrees of true strain (e) 0.26, 0.56, 1.00, 1.71 and 2.14. It has been shown that structure formation of the studied steel during CRF consists of three stages: formation of the lamellar structure of austenite, formation of the trapezoidal structure, and formation of the equiaxial grain structure. The kinetics of the strain-induced α’-martensitic transformation is related to the stages of structure evolution. Hardness, ultimate tensile strength and yield strength uniformly increase in all stages of structure formation with a significant decrease of elongation to fracture during the first stage of structure formation while the value of elongation to fracture remains constant in the subsequent stages of deformation. Impact strength of fatigue cracked specimens (KCT) decreases sharply at the first stage of structure formation and smoothly increases at the second and third stages. However, the impact strength of V-notch specimens (KCV) continuously decreases when deformation degree increases in the overall investigated deformation range.

“…It is proposed at the level of relative deformation, equal to one hundred percent, or true: 𝑒 кр ≈ 1. In [19], it was noted that the self-organization of the structure with the formation of cells already begins with the deformation of ferrite steel 09Г2С and with an average degree of cold deformation ε of the order of 15... 35%. With a further increase in deformation, the cell walls become thinner and their size decreases.…”

In this study, a structural-deformation analysis of the process of crack development is performed, on the basis of which an engineering methodology is developed for assessing the endurance limit and resource of large-sized structures. A simple analytical dependence (correlation аналитическая зависимость) was obtained, which allows one to determine the critical size of macrocracks for ferritic-pearlitic steels without using the well-known Griffith formula. The results of calculating the cracks critical lengths of various steels depending on their yield strength are presented. The analytical dependence of the calculation of the fatigue limit for the most dangerous symmetric loading cycle according to the standard set of mechanical characteristics of ferrite-pearlite steel is presented. The obtained results make it possible to calculate the endurance limit of structural elements of marine equipment and other structures subject to cyclic loads
