Abstract

Microstructural aspects of composites such as particle size, shape, and distribution play important roles in deformation behavior. 3D visualization of porosity and Fe-rich inclusions in three dimensions is critical to a thorough understanding of fatigue resistance of metal matrix composites (MMC) because cracks often initiate at these defects. In this paper we have used X-ray synchrotron tomography to visualize and quantify the morphology and size distribution of pores and Fe-rich inclusions in a SiC particle reinforced 2080 Al alloy composite. The 3D data sets can also be used for image-based finite element simulations to predict the onset and evolution of damage.
