Abstract

The paper presents technological schemes of electromechanical processing (EMP) and examines formation specifics of high strength steel structures in the area of thermomechanical highly-concentrated strain on the root and flanks of external and internal threads. Testing results of EMP implementation are described. Materials of this paper are of practical value to specialists in various fields, related to the issues of improving threaded joint reliability.
