Effect of chemical composition on the behavior of selected iron aluminides

Popis výsledku v původním jazyce

The influence of chemical composition on the deformation resistance of iron aluminides was studied by the plastometric tests on three types of Fe?40at.%Al based materials; especially the influence of zirconium and boron, respectively effect of fine TiB2particles addition was investigated. All materials were prepared using the identical procedure (laboratory melting and casting under vacuum to the same cast?s shape), which is methodologically valuable. The same method of sampling, sample preparation andanalogous testing conditions were used for subsequent experiments, which took place on identical Gleeble 3800 plastometer. The samples were pre-heated to a temperature of 1200 °C and then deformed at temperatures from 800 to 1200 °C, the nominal strainrate was 0.05 s-1, 0.4 s-1, 4 s-1 and 30 s-1. The activation energy values for hot forming of all three types of coarse-grained cast material (Fe-40Al, Fe-40Al-Zr-B, Fe-40Al+TiB2) were obtained from the peak values of stress-strain curves
