Description
Summary:The paper presents the results of studies of the kinetics of accumulation of fatigue damages in titanium VT1-0 and titanium alloy OT4 by acoustic emission method (AE). Identification of the sources of acoustic emission (dislocations, micro- and macro-cracks) is based on the methodology developed by the authors. According to the activity of various types of acoustic emission sources, the stages of fatigue are identified in conditions of flat cantilever bending. The data of the acoustic emission analysis were experimentally confirmed by the results of microstructural studies.
