Abstracts
In this study, damping and mode shapes were investigated after boriding and austempering the spheroidal graphite cast iron (SGCI). The samples were boronised and austempered at 900℃ for 2 hours by employing the pack cementation method. The samples were cooled and tempered in a salt bath at 250℃ and 375℃ for 1 hour. Once the boriding and austempering processes were completed, the samples were cooled at room temperature and washed with plenty of water. The modal frequencies, damping ratios and mode shapes of these samples exposed to different heat treatments were acquired by using the experimental modal analysis (MA) method. The same characteristic features were acquired with the finite element method (FEM), and the results were compared. It was found that after the heat treatment the sample austempered at 250oC had a harder surface and a higher frequency than other samples.
