FATIGUE FAILURE OF NATURAL COMPOSITE MATERIALS

The paper studies the fatigue characteristics of samples of low-carbon low-alloy steels, normalized and cooled from the intercritical temperature range at different rates. Fractographs of the fracture surfaces of the samples after fatigue tests are presented. The fatigue fracture surfaces are analyzed in detail. It is concluded that biphasic ferritic-martensitic steels have a higher resistance to fatigue failure as compared to steels with the ferrite-pearlite structure.

Acknowledgments: The study was performed with the use of the equipment installed at the Plastometriya collective use center affiliated to the IES UB RAS, Ekaterinburg, under the Arctic program of UB RAS, project BP 18-9-1-20.
