Investigation and characterization of thermal properties of a metal matrix composite reinforced with a metallic glass foam (Ni60Nb20Ta20)

  • The metallic glass presented in this work with alloy composition Ni60Nb20Ta20 (at.-%) obtained its amorphous structure through a powder atomization process and was processed into an open-porous foam using laser powder bed fusion. Subsequently, the open-porous structure was infiltrated with an AlSi12 eutectic aluminum alloy by gas pressure infiltration. For manufacturing processes and applications, knowledge of thermal properties of the metallic glass foam as well as metal matrix composite is essential. Therefore, characteristics of thermal expansion were determined experimentally by dilatometry, specific heat capacity by differential scanning calorimetry and thermal conductivity by laser flash analysis. Thermal expansion as well as specific heat capacity are measured for the metallic glass foam as well as infiltrated composite. Laser flash analysis method was applied to the infiltrated composite only, as this method is not suitable for an open-porous structure.
