摘要：

Rapidly solidified Al-3.9V-0.1 Zr alloy is a single sol-id solution.The metastable limited solid solubility ofsolute V in Al reaches 3.9 wt-% under about 10;K/scooling rate.A strong age hardening response have beenobserved in this alloy.A large amount of dislocation linesand loops were observed in the alloy aged at 100-150℃:and an age peak occurs at 450℃,the hardness value in-creases by a factor of 2.The precipitate which is responsi-ble for age hardening is identified to be Al;（Al）.
