Sažetak
The effect of high temperature tempering on austempered ductile iron was investigated in this paper. Five samples of ductile iron with 0, 51% wt. % Cu were austempered without subsequent high temperature tempering and five samples of same ductile iron alloy were austempered with subsequent high temperature tempering. All samples were austenitized on 850°C for 60 minutes. Austempering was done on 250°C, 331°C and 420°C for 30, 68 and 120 minutes. High temperature tempering was done on 500°C for 60 minutes. At the end, all the samples were air cooled to room temperature. Tensile strength and elongation were measured on all samples thus compering results with and without high temperature tempering. Results showed that samples with subsequent high temperature tempering have slightly lower tensile strength and significantly higher elongation compered to samples without subsequent high temperature tempering. Also, samples with subsequent high temperature tempering show more uniform tensile strength when compared to samples without subsequent high temperature tempering.
