Summary

In previous investigations we did a partial substitution of Mg2Ni by third alloying elements (Mn, Fe, Co, Cu, Al, Zn, Ag) for the purpose of making its hydride unstable, and samples of the ternary alloys were also rapidly-solidified and mechanically-ground in order to improve protium absorbing/desorbing characteristics by microstructural homogenization. Obtained results show that the substitution by Mn improves protium absorption characteristics at low temperatures. It is expected that Mn replaces part of Ni site in Mg2Ni alloy because Ni and Mn are completely soluble in each other at high temperatures. Therefore, in this study, for further improvement of Mg-Ni-Mn ternary alloys, the Mn content was altered, and their protium absorbing/desorbing characteristics were investigated.
