Abstract

This presented diploma work describes the characteristics of 34CrMo4 material, and the properties and microstructures before and after cyclic loading. The obtained results from mechanical properties revealed an increasing of strength of the tested material after cyclic loading. Detected fracture surface showed typical quasi-cleavage fracture. Directly under surface of material the structure was ferritic, and that was changed to ferritic-pearlitic, and then went over to martensite structure. The decarburization and segregation were also observed under the surface.
