Paper Abstract

Hard x-ray tomographic images with high spatial resolution were obtained at he European Synchrotron Radiation Facility in Grenoble. They clearly display damage initiation within materials submitted to monotonic tensile test. Strain- induced cracks with opening of less than 1 micrometer are detected, as are slight differences in composition between constituent phases. These observations are based on the Fresnel diffraction fringes associated with local jumps in the optical phase of x-rays transmitted through the sample. The high lateral coherence of third generation synchrotron radiation sources is essential for the application of this instrumentally simple technique.
