Solid-state synthesis of Mg₂Si via bulk mechanical alloying

Solid state synthesis via bulk mechanical alloying is proposed to fabricate Mg₂Si alloy bulk samples. Starting from the powder mixture of flaky large-grained powders and silicon Mg₂Si was reactively synthesized by the bulk mechanical alloying. Through XRD and TEM, the synthesized Mg₂Si was characterized with respect to phase and structure. Although total reactivity is strongly dependent on mechanical behavior during bulk mechanical alloying, single phase Mg₂Si can be successfully synthesized from locally reacted embryo by low-temperature annealing of the BMA samples.
