The formation of Bi-Li alloy and its potential mechanism to improve the hydrolysis kinetics of Al had been presented in the paper. Bi-Li alloy could exist steadily and deposited on Al surface uniformly from XRD and SEM-EDX results because Bi-Li alloy had low melting temperature. The formation of Al- BiLi3microstructure created active sites which produced galvanic micro cell of Al and Bi in the hydrolysis process. Therefore, hydrolysis performance of Al- BiLi3 composites was significantly improved with BiLi3 content increasing.
