| Abstract | This chapter introduces the experimental procedures utilised to characterise austempered ductile irons obtained in the present thesis. The experiments here described were also used to validate models included in latter chapters. Fig. 2.1 is the general ow c hart of experimental procedures. A ductile cast iron produced in a commercial foundry using electric melting has been used for the experiments. Its chemical composition is Fe-3.55C-2.5Si-0.55Mn-0.15Mo-0.31Cu-0.042Mg wt%. Solid cylindrical specimens with dimensions 8 mm diameter and 12 mm length were machined from a keel block for heat treatments. All samples which required heat treatment in furnace, either for homogenisation or for austempering treatment, were sealed in quartz tubes under a partial pressure of argon to prevent o xidation. Homogenisation consisted in holding the samples at 1000 C f o r 3 d a ys 1 |
