Influence of Cumulative Plastic Deformation on Microstructure of the Fe-Al Intermetallic Phase Base Alloy

Abstract: This article is part of the research on the microstructural phenomena that take place during hot deformation of intermetallic phase-based alloy. The research aims at design an effective thermo -mechanical processing technology for the investigated intermetallic alloy. The iron aluminides FeAl have been among the most widely studied intermetallics because their low cost, low density, good wear resistance, easy of fabrication and resistance to oxidation and corrosion. There advantages create wide prospects for t… Show more

“…In terms of lightening, it has been shown previously that density decreases with aluminum content [45], which was aimed at in the first place in the choice of our compositions. However, it was previously noted [46] that problems arise in the production of high-aluminum Fe–Al alloys, hence the use of vacuum or powder-metallurgy techniques. These problems include excessive metal oxidation, and the occurrence of significant internal stresses on parts, resulting in cracks and porosities.…”

“…The MAXStrain unit has been used, for example, to investigate the controlled microstructure evolution, or to investigate the possibility of grain refinement in Al [5,6], Mg [7] and Ti [4,8] based alloys and also in the case of intermetallic alloys [9]. This technique has also been used to investigate of the grain refinement possibilities of microalloyed steels [3,[10][11][12][13].…”

“…The aim is to achieve the controlled development of the microstructure and the smallest possible average grain size by a suitable choice of test parameters and deformation conditions. Various technical metallic materials were processed in this way, starting with aluminium [2,5] through titanium alloys [6,7], steels and another special alloys [8][9][10][11]. The phenomenon of the "first stress peak" in microalloyed austenitic and ferritic steels was also studied within the MAXStrain issue [12].…”
