We analyze the causes of the in-service loss of integrity of drill pipes made of G105 steel connected with their premature stress-corrosion fractures. In this case, the mechanical characteristics of steel are satisfactory, except a somewhat lowered e

We propose a microfractographic method for the evaluation of the technical state of rolled carbon steels after long-term operation based on the construction of a correlation dependence between the brittle fracture resistance and, in particular, impac

We investigate 12Kh1MF steel of two bends of the main steam pipelines of thermal power plants. It is shown that they are damaged by the mechanism of intergranular fracture due to creep. In one of these bends, despite the agreement of the metal in all

We compare the mechanical and corrosions characteristics of 17G1S steel in the intact state and after its operation for 40 yr in a gas main. The low sensitivity of the strength characteristics of steel and its modulus of elasticity and much higher se

We determine the impact toughness and study the fractographic characteristics of the fracture surfaces of the old and repair steels (produced in 1906 and 1944, respectively) of the hyperboloid gridshell Shukhov water tower in Mykolaiv, some elements

We study the influence of repeated normalization of operating 36G2S steel of drill pipes on their structure, fatigue-cracks growth, and fractographic features of fracture. It is shown that the crack-growth rate decreases and brittle elements in the f

We have investigated the mechanical properties of 15Kh1M1F heat-resistant steel after long-term operation in steam pipelines of steam power plants. The anisotropy of its strength and plasticity characteristics as a result of degradation has been dete
