Title: Influence of nanoadditives on the structure and properties of austempered ductile irons
Keywords: nanoadditives, austempered ductile iron, microstructure, bai

Abstract: The microstructure and properties of austempered ductile iron with nanosized additives: titanium nitride + titanium carbonitride TiN + TiCN and titanium nitride TiN are investigated. The samples of unalloyed ductile iron are put under austhempering at the following conditions: heating at 900oC, 1 h and isothermal retention at 280oC, 2 h with the aim to achieve lower bainitic structure. The microstructure of the iron is investigated by metallographic analyses. The Vickers hardness testing, impact toughness strength examination and wear resistance at a fixed specimen study are carried out. The retained austenite quantity in the austempered ductile iron before and after tribological testing is determined by X-Ray analysis. The influence of the nanosized additives on the microstructure, mechanical and tribological properties of the iron is investigated.
