Microstructure of rapidly solidified and hot-pressed Al-Fe-X alloys

Popis výsledku v původním jazyce

Rapidly solidified aluminium alloys are promising materials for many technical applications. The main advantages of aluminium alloys alloyed with transition metals, such as Ni, Fe, Cr or Mn, are a good strength-to-weight ratio, a relatively low price, improved mechanical properties and a thermal stability. Mechanical properties of these alloys can be improved with rapid-solidification techniques. In this work, a production method employing melt spinning, cryogenic milling of melt-spun ribbons and the subsequent hot pressing was tested. The Al-11Fe, Al-7Fe-4Cr and Al-7Fe-4Ni alloys were processed in this way. The microstructure and mechanical properties of the prepared alloys were compared with the cast materials of the same composition. The results showed that the proposed technology can lead to a significant microstructure refinement and hardness improvement of the investigated alloys, when compared with the as-cast state. In the case of the Al-Fe alloy, a local coarsening of the Al13
