Solid-state synthesis of magnesium base alloys

Magnesium alloys are expected to be used for light-weighed structural members or parts and to improve their functionality per a unit weight. Since conventional processing are often inadequate or incompatible to synthesis and microstructure control, solid-state synthesis is proposed as a promising methodology for magnesium alloy design, and developed on the route of the bulk mechanical alloying. Among various magnesium alloys, Mg-Ni system is employed here to demonstrate the validity and effectiveness of the present solid-state synthesis via bulk mechanical alloying. Single-phase Mg₂Ni is successfully synthesized by the present method. In addition, both chemical modification by the third element addition and formation of non-equilibrium Mg₂Ni phases are performed in the present solid-state synthesis, aiming for further advancement of original functionality for Mg₂Ni alloys.
