THE COMPARISON OF THE MICROSTRUCTURE AND THE MECHANICAL CHARACTERISTIC OF AUSTEMPERED DUCTILE CAST IRON AND STEEL SUBJECT TO DYNAMIC DEFORMATION USING THE TAYLOR TEST

The article attempts to compare the resistance of austempered ductile cast iron and S215 steel to dynamic loads. The samples were subject to research using the Taylor test methodology at different speeds of deformation, in order to determine the c...
