Self-Healing in rapidly solidified aluminium alloys

R
apid solidification of alloys can be preformed e.g.
by melt spinning method. This process leads to
several changes in the microstructure, the main are
increase of solubility of allying elements, microstructure
refinement and formation of metastable phases such
as quasicrystals. These microstructural features have
prommising potential for self-healing behaviour of
the material. Decomposition of supersaturated solid
solution can lead to precipitation healing mechanism
that was already proven in underaged aluminium alloy.
Decomposition of quasicrystals can also cause closing
of the crack in the alloy. The self-healing behaviour in the
Al-Cr-Fe alloy was observed in this work. The alloy was
studied by LM, SEM and TEM. Correlative SEM/AFM
microscopy was also performed.
