The Effect of High-temperature Deformation on the Structure of Iron Aluminides
Original language description
The iron aluminides are very perspective materials with many advantages and of course also disadvantages. One way, how to improve mechanical properties of iron aluminides, is doping of binary alloy by alloying elements, which can form strengthening precipitates. Depending on their size the precipitates of secondary phases can block dislocation movement or act as strengthening phase as known in composite materials. One from many properties, which is important to know before a new type of materiál is used in structural applications, is its deformation behaviour. In present páper there was studied the structure of Fe-25AI-5Zr (in at. %) sample in as cast statě and in states after high-temperature deformation at 600 and 800 °C in detail. A high resolution SEM equipped with EDX and EBSD was used for the study of structure. It was measured that huge grains are presented in the structure of as cast statě. After deformation at 600 °C there were still observed huge Fe3AI-matrix grains, but strongly deformed as is visible in IPF maps. Also formation of subgrains due to deformation is obvious. Deformation at 800°C led to formation of small grains due to recrystallization. Higher deformation degree in non-eutectic areas led to preferential recrystallization while Fe3AI phase in eutectic regions remained deformed (nonrecrystalized).
