In this work, Fe-Al-Si alloys were prepared by reactive sintering. The contents of silicon and aluminium ranged between 0-30 wt-% and 10-40 wt-% respectively. Aluminium, silicon and AlSi30 master alloy powders prepared by mechanical machining and/or milling and commercial powder of high purity iron were used for sintering. Powders were blended and pressed at room temperature. Sintering was carried out at 950uC for 60 min. Compact low porosity products without unreacted components were prepared, if a powder mixture contained 15-20 wt-% of silicon and 20-25 wt-% of aluminium. It was shown that these materials contain two phases (Al 2 FeSi and AlFeSi). Hardness of the alloys increased with growing silicon content, while the increase in aluminium content reduced the hardness.
