AlSi10Mg is widely used aluminum alloy for additive manufacturing and highly demanded for diverse lightweight applications for example in aerospace and automotive. However, the manufacturing method and thus the microstructure, silicon phase size/morphology, and precipitation hardening significantly affect the mechanical properties of this alloy. Furthermore, the reinforcement of aluminum alloys with hard particles represents an effective approach to fully exploit the potential of AlSi10Mg and its mechanical performance. For this reason, this work aims to produce particle-reinforced AlSi10Mg alloys containing 5 vol.-% aluminum oxide (Al2O3) and silicon carbide (SiC) by means of powder metallurgy route including high-energy ball milling (HEBM) and field-assisted sintering with subsequent precipitation hardening. The investigation focuses on the influence of the reinforcement type and the milling conditions, mainly the milling atmosphere and process control agent, on the final material properties. To reach this, a comprehensive analysis of the HEBM composite powder, the sintered and the heat-treated part is necessary, especially with regard to the distribution of the reinforcement particles in the matrix, chemical/phase composition, microstructure characteristics and mechanical properties. This will be mainly performed by light and electron microscopy, x-ray diffraction, hardness and quasi-static tensile tests aiming to establish microstructure-property correlation.
