An alloy containing Al - 3wt.% Cr - 3wt.% Fe 0.8wt. % Ce, was prepared by melt spinning. Structure of obtained ribbons was observed by light, scanning and transmission electron microscopy.
It was found out that the structure is very fine. Microhardness of cross sectioned ribbons was also measured.
Defects in structure were determined by positron annihilation spectroscopy. The thermal stability of the alloy was observed by comparing rapidly solidified ribbons and ribbons annealed at 400 degrees C and at 500 degrees C for 100 h.
