摘要：

The fatigue test results and the mechanical characteristics in static tension are obtained for specimens of titanium alloys belonging to the known classes of materials with a reference globular or bimodal microstructure and the so-called fine-grained beta-transformed microstructure provided by the rapid heat treatment technique. The microstructure of the materials under study is analyzed. The microstructural parameters responsible for the fatigue strength of particular material have been found. The comparison is made between the fatigue limits obtained experimentally and calculated using the models previously developed by one of the authors.
