Structure and plasticity in hot deformed FeAl intermetallic phase base alloy

This paper constitutes part of research conducted on the possibility of forming alloys based on intermetallic phases from the Fe–Al system via thermoplastic processing. Insufficient plasticity, which is an inhibitor of further development of these intermetallics as construction materials, makes the range of their applications limited.In the paper, an analysis is conducted of the influence of deformation parameters on the structure of an alloy of Fe–Al with the B2 type structure. Axi-symmetric compression tests were carried out at temperatures ranging from 600 °C to 1200 °C and at a deformation rate from 0.001 s1 to 10 s− 1. Structural examination was carried out using light microscopy and transmission electron microscopy. A quantitative evaluation of the structure was made with the use of “Met-Ilo”. The results obtained will be used for the development of mathematical models determining the influence of deformation parameters on the alloy structure.
