AB This work deals with comparison of two production methods on microstructure, phase composition and mechanical properties of intermetallic based on Fe-Al-Si which are appropriate materials for high-temperature applications. A conventional metallurgical process - casting - was compared with a novel processing method, based on ultra-high energy mechanical alloying (MA) and spark plasma sintering (SPS) in order to prepare FeAl20Si20 (in wt. %) alloy. The influence of production route was observed. Via MA + SPS can produce a material of the same phase composition but with significantly better mechanical properties. Negligible porosity, fine-grained and homogeneous structure are the reasons.
