Functionally graded steels were produced via an electroslag remelting process using plain carbon and austenitic stainless steels as electrodes. The charpy impact resistance of functionally graded steel specimens in the form of a crack divider was investigated. The results obtained show that the impact energy of specimens depends on the type and volume fraction of the containing phases. According to the hardness profile and the area under the stress-strain curve obtained from the tensile test, two mathematical models have been presented for predicting the impact energy of specimens using the rule of mixtures. There is good agreement between experimental results and those acquired from two models.
