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 Mg,Si can be successfully synthesized from locally reacted embryo by low-temperature annealing of the BMA samples.
