Abstract: Rapidly solidified(RS) FVS0812 alloy powder was obtained by means of multi-stage RS powder-making device. The effect of elevated temperature (200~500℃) on the mechanical properties of the cold deformed specimens was investigated. The results showed that the strength increases significantly after being exposed at 200~500℃. This abnormal behaviour can be attributed to the clusters of the transition metal solute—iron in aluminum matrix, forming during the hot deformation or heat treatment.
