| Abstract Scope |
Laser powder bed fusion (L-PBF) CuSnNi components have possible applications in the aerospace industry as well as in the electrical resistance welding systems. The goal of this research is to investigate the influence of printing and post-processing parameters on the mechanical behavior of the L-PBF CuSnNi alloy. Samples for tensile, compressive, and hardness testing were printed on the EOS M290 on different orientations. The investigation was conducted on as-printed and heat-treated samples. To corelate the printing and post-processing parameters with the mechanical properties, light and electron microscopy investigations were performed on both cross-sectioned and fractured samples. Pending on the sample orientation the as-printed samples showed a maximum tensile strength of 245 MPa and a maximum modulus of elasticity of 104 GPa. The printing defects affected both sets of samples (as-printed and annealed) and their influence on the mechanical properties will be discussed. |
