| Popis: |
The corrosion behaviour of as-rapidly solidified and heat treated AI 8Ni-2Co alloy ribbons produced using melt spinning technique was investigated. The decomposition behaviour of the rapidly solidified ribbons was followed up using x-ray diffraction, differentialscanningcalometry. microhardness, and metallography. The stable phases which are generally formed in conventional solidified alloy in the as cast condition, were not detected in the as-rapidly solidified specimens. Instead, super-saturated solid solution α-AI was present in addition to fine dispersoids of A19(CoNi)2. The corrosion behaviour was investigated through potentiostatic technique in 3.5% NaCL aqueons solution. The corrosion rate was the lowest in the as-rapidly solidified condition and increased with increasing the annealing temperature as a result of the formation and coarsening of the intermetallic Al3Ni. |
