Magnesium chips were coated with silicon powder using a binder, and injection molding was performed using silicon-coated chips as the raw material. Microstructural analysis of the products revealed that all added silicon (Si) precipitated as Mg2Si particles, with no voids present at the interfaces between the Mg2Si particles and the matrix. Furthermore, the hardness and Young’s modulus of the products increased with higher Si content. The Young’s moduli followed the rules of mixtures.
