Aging Process of Rapid Solidified Nanocrystalline AlFeVSiNd Alloy Ribbon

The variation of the microstructure of rapid solidified Al Fe V Si Nd nanocrystalline alloy ribbon during aging process was investigated by TEM and X ray diffraction. With the increase of temperature, the microstructure of rapid solidified Al Fe V Si Nd nanocrystalline alloy ribbon changes. Firstly, the G P zones appear. Then, Al 8Fe 4Nd phase begins to be dissolved and α Al 13 (Fe,V) 3Si phase is precipitated in the sametime. The mechanical properties were measured before and after aging process. It is found out that happened age harden phenomenon in tradition Al alloys takes place in the aging process of the rapid solidified Al Fe V Si Nd nanocrystalling alloy ribbon.
