Microstructure and Hydrogenation Property of Mg-6.7 mol% Ni Alloy

Article Preview

The relation of the microstructure and hydrogenation property of a hypoeutectic Mg-6.7 mol%Ni alloy consisted of primary Mg crystal and Mg2Ni phase has been investigated. In the case that the specimen has a very fine structure, hydrogen is hardly absorbed into the specimen. The growth of both the primary Mg crystal and Mg2Ni phase allow easy hydrogen penetration, but the growth of the primary Mg crystal is more effective. The highest hydrogenation rate and absorption amount of 5 mass% are obtained when the Mg2Ni phase has a rounded shape.
