Abstract

The mechanical properties of as-sintered and heat-exposed polycrystalline Mg2Si were investigated. The strength of the as-fabricated specimen depends on the surface flaws. After heat exposure in Ar atmosphere, oxidized products formed, mainly consisting of MgO. The strength increased after the heat exposure, and the surface oxidation product filled the surface cracks. After the surface oxidation products were removed, the strength and TE properties were the same as those of the as-fabricated specimens.
