Mikrostructure transformations in austempered ductile iron during deformation by dynamic hardness test
Abstract
The article presents effect of investigations on microstructure changes in austempered ductile iron under the effect of dynamic surface deformation. Mechanical properties research covered the heat treated ductile iron characterised by a tensile strength of 1049 MPa and elongation of 16% with high austenite content in microstructure. The task to be performed consisted in FEM simulation of the deformation effect, using a steel ball pressed dynamically into the examined material with experimental verification of the obtained results. The ADI microstructure was examined by LM, SEM and magnetic measurement technique. The kinetics of the deformation-induced transformations was also analysed.
