Abstract
Porous single phase Al12Mg17 alloy was fabricated by cooling in to water after powder metallurgy sintering for use as
hydrogen storage fuel cell. Because Al12Mg17 phase has more theoretical hydrogen storage capacity than the phases
occurred such as Al3Mg2 and R(AlMg) in microstructure of the alloy. The pore morphologies, microstructure and phases
were investigated. It was seen that phases such as Al12Mg17, Al3Mg2 and R(AlMg) occur in the microstructure of the sample
fabricated by powder metallurgy sintering. The formation of Al3Mg2 and R(AlMg) phases was blocked by speed quenched
into water after sintering and single phase Al12Mg17 was obtained.
Keywords
