摘要
Based on the results of comparative studies of the fatigue life of wire semiproducts from titanium-based and titanium nickelide-based alloys and also from 06Kh19N9T steel, it was shown that the fatigue properties of the alloys are dependent on their structure, the deformation mechanisms of the materials, and the degree of reversibility of a deformation induced in a sample. The concept of a critical strain is used corresponding to the onset of the development of a slip in a material and to the transition of the material forming from reversible deformation mechanisms to the mixed mechanism including the slip. The correlation is established between the critical strain and the fatigue life of the alloys under study.
