Visualization of porosity in 3D is critical to a thorough understanding of the microstructure and properties of PM steels. Here we describe two techniques that can be used to visualize porosity in 3D: serial sectioning and X-ray tomography. Both techniques can be used to visualize porosity, as well as to quantify the pore fraction and degree of pore interconnectivity. The use of image-based finite element simulations, using 2D images of the microstructure, is also described. This is an invaluable tool in correlating the actual pore structure with the mechanical properties of the PM steel.
