Evaluation of fractures in MAR-M509 alloy samples after fatigue strength tests
Journal Title: Archiwum Odlewnictwa - Year 2010, Vol 10, Issue 3
Abstract
The paper presents the result of fracture analysis in MAR-M509 samples after high-cycle bending fatigue strength tests. Microstructural tests were carried out with a scanning electron microscope. To identify carbide phases a quantitative analysis of the chemical composition was made. The fracture surface and the surface in a plane perpendicular to the fracture surface were observed. It was discovered that the crack initiation and propagation occurs on carbide separations.
