Abstract:Microstructures and precipitation process of rapidly solidified foil powders of Al-Fe-Cr-Zr have been investigated using TEM, X-ray diffraction, optical microscope and hardness measurement. The results indicate that(1) featureless structure can be obtained easily in Al-Fe-Cr-Zr alloy under rapid solidification condition;(2) Al13Cr2, Al3Zr and Al3(Fe,Cr) phases precipitate during heating;(3) metastable Al3Zr has noticeable precipitation strengthening effect.
Key words: rapid solidification powder metallurgy heat-resistant aluminum alloy
