4. Summary

In the study high cycle fatigue element model of laminate AA2519/AA1050/Ti6Al4V produced by explosive bonding was analyzed. Research results the impact of the applied heat treatment on the laminate. The results indicate the beneficial effect of the applied heat treatment. It showed an increase of the heat treated samples, both notched and smooth samples. For samples with a hole increase in fatigue life were observed only in the tests above  max =150 MPa. The highest, 30 % increase in the durability of these samples occurred during testing at  max =250 MPa. The analysis of smooth heat-treated samples showed an increase in stability after the heat treatment of 20-30 % of the range  max =175-350 MPa. The results of electron microscopy studies of surface fatigue fracture allowed to determine the location of sources of fatigue cracking, which in the case of samples without heat treatment were in the area of border merger Ti6Al4V-AA1050. Sources of cracking in the elements after the heat treatment were located within the edge of the samples. The project is carried out under Project PBS2/A5/35/2013 funded by the National Research and Development Centre. References [1] Bataev I.A.,.
