Ball-milling of Mg2Ni under hydrogen — Kyushu University

The intermetallic compound Mg 2 Ni is milled under hydrogen in a high-energy planetary mill. The resulting material is a mixture of heavily deformed Mg 2 Ni, low-temperature Mg 2 NiH 4, and, possibly, high-temperature Mg 2 NiH 4 structures. The relative amount of each phase depends on the initial hydrogen pressure in the milling vial.
