4.Mineral Processing
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 production of ADI cast iron, must meet demanding metallurgical properties. These are, above all, regular and uniformly distributed graphite spheres in the matrix. One of the ways to influence the metallurgical quality of ADI cast iron is the action of a magnetic field, which leads to the improvement of the metallurgical and mechanical properties of ADI cast iron. The article deals with the influence of a magnetic field on the mechanical properties of ADI in the process of isothermal hardening. In isothermal quenching, after austenitizing, the quench is first cooled to a lower temperature and then the temperature of the quenching medium is raised to a higher temperature. The entire process is carried out in the presence of a magnetic field. The mechanical properties and microstructure were compared with the conventional manufacturing process. In this way, an increase in the mechanical properties and a refinement of the cast iron structure was achieved.
