摘要

A novel recycling process was developed to produce vanadium aluminum (AlV55) alloy using vanadium aluminum (AlV65) alloy scrap and aluminum (Al) under vacuum. The theoretical calculation indicates that Al can be evaporated under vacuum. Excessive Al would be consumed during melting process when the reaction temperature ranges from 1823 to 2123 K, according to the theoretical calculation, which indicates Al could evaporate under vacuum. The experimental results present that Al was effectively dissolved in molten AlV65 alloy, the impurities (N, O, and C) decreased and the content of V increased gradually with reducing Al addition.
