    Abstract

    A new aluminum alloy, named Scalmalloy®, was specifically developed for the Laser powder bed fusion (LPBF) process and aerospace applications with enhanced mechanical performance. This paper proposes an innovative testing method to study the mechanical properties of Scalmalloy® and to compare them with those of AlSi10Mg, a typical casting alloy with good weldability. In situ tensile tests inside the SEM were performed on the two alloys to track damage evolution. This enables to continuously observe the crack nucleation, the propagation through the imperfections typically found in AM and any microstructural changes. To determine the fracture mode and evaluate the possible correlation between the fracture mode and mechanical properties, fracture surfaces of the samples were studied, and the fracture mechanics are discussed. The analysis of the static behavior was completed with micro-tensile and hardness tests. The results obtained for the two aluminum alloys using this range of experimental methods are analyzed and compared with literature studies of Additive and Conventional Manufacturing.
