“…The technique developed by us [1] makes it possible to evaluate the bearing capacity of welded joints at high temperature, at the stage of formation and development of LR, taking into account the relaxation ability of the material, under conditions of low-frequency lowcycle loading (low-cycle loading with long time exposures at the creep temperature).…”

“…The operation of power equipment at temperatures above 500 0 C requires a comprehensive assessment of the heat-resistant properties of welded joints, which determine the reliability, durability and safe operation of the structure [1]. When carrying it out, the influence of the main structural and mechanical factors should be taken into account: the initial defectiveness of the material; stability of the structure and properties during operation; type of stress state; operating conditions, etc.…”

The problem of increasing the resistance of welded joints of power equipment against local destruction in the conditions of non-stationary mode of high-temperature operation is relevant. In the studies performed, the analysis of the causes and nature of LR was carried out from the standpoint of classical physics of high-temperature deformation and intergrain destruction by the creep mechanism. Most of the test methods developed simulate just such loading conditions. However, the most objective assessment of the susceptibility of the welded joints to LR can be given by the method of testing welded joints under conditions of high-temperature low-frequency low-cycle loading.
