3D Investigation of Fatigue Crack Morphology and Crack Growth of Iron-Based Materials via Synchrotron X-Ray CT

Abstract:

The present paper addresses a 3D investigation of a complicated fatigue crack profile and crack growth behavior in cast Hadfield high manganese steel by in-situ X-ray computed tomography (CT) experiments. In-situ loading experiments were performed on fatigue pre-cracked samples at the X-ray beamline BL13W1 of Shanghai synchrotron radiation facility in China, and high-resolution phase contrast imaging technique was applied to obtain the 3D images. Based on the rendered 3D images at varied loading levels, various crack features and the interactions of the fatigue crack with casting pores were identified and analyzed.
