Abstract Porosity plays an important role in the properties of powder metallurgy products and castings. Nowadays, there are several methods for determining porosity: optical microscopy, computed tomography, density measurement according to Archimedes’ principle. The aim this study is present advantages disadvantages different porosity testing relationships between results. With conventional met...
