Abstract
Nowadays, austenitic stainless steels due to its properties are widely used in various applications. In powder metallurgy technology one of the key factors, affecting the pressing process, the sintering phenomena and the final properties of sintered parts, is the shape and particle size of the powders. The article presents the results focused on analysis of the oxidation process of austenitic stainless steel. Powders of the same chemical composition, however of different shapes, depending on the manufacturing technique i.e. spherical after inert gas atomization and sponge after water atomisation, were investigated. Moreover, the influence of particles’ size from different ranges 40-56µm and 80-100µm on the oxidation behaviour was analysed. Thermal measurements, differential scanning calorimetry (DSC) and thermogravimetry (TG), were performed by the STA 409 CD (Netzsch) advanced coupling techniques. Moreover, dilatometry technique has been used for analysis the influence of the size and shape of particles on the sintering process. Sinters oxidation phenomena has also been determined. Based on the obtained results, it was found that both shape and size of powders have a significant influent on the oxidation processes of powders as well as sinters of the austenitic stainless steel.
