Cyclic fracture parameters of seminatural cast iron specimen with weld

Abstract

The article presents the results of experimental and analytical investigation of high-cycle fatigue of seminatural cast iron specimen. The microstructure and mechanical properties have been identified for basic material and weld. The cyclic fracture parameters have been determined from the beginning of crack formation until the complete destruction. Fracture analysis obtained by scanning electron microscope allowed to briefly investigating the fracture parameters.
