Austempered Ductile Iron (ADI) is a promising material whose structure is obtained by isothermal processing, i.e. isothermal decomposition of austenite in the bainitic range. It is used in various industrial fields. It is characterized by an excellent combination of tensile strength and ductility, exceeding the properties of quenched and tempered steels in the strength range of 800 - 1500 MPa. Its production is problematic because the ferritic or ferritic-pearlitic ductile iron (SGI), which is the basis for the pr...

Cast iron GG30 (EN-GJL-300C) has excellent mechanical properties and good machinability. It can be used in many industries such as hydraulics, engineering, automotive, oil and gas mining, and processing. It is suitable for the production of compressor and pump components. Return material, technological residue, iron scrap, fractional cast iron, liquid metal, and alloying components can be used as input raw materials in the production of cast iron, the first three were taken into account in the analysis. In practic...
