The demand for additively manufactured AlSi10Mg alloy for fabrication of structural components in automotive industries is ever growing due to its superior tensile, fracture toughness, and corrosion properties compared to the alloy processed through conventional subtractive manufacturing techniques. The literature on the fracture toughness of AlSi10Mg correlating with microstructural characteristics, as a function of process variables in laser beam melting (LBM) is scarce. Hence, the fracture toughness of AlSi10Mg components produced via LBM has been investigated in the present work. The alloy was fabricated in two build orientations – in XY and Z directions and in two different build atmospheres, of argon and nitrogen. The effect of build atmospheres on the fracture toughness of the fabricated AlSi10Mg alloy in various built orientations was studied. Detailed fractographic analysis of tested specimens was performed to understand its fracture characteristics.
