The Use of Selective Laser Melting to Increase the Performance of AlSi9Cu3Fe Alloy

Original language description

For the first time, the comprehensive characterization of the additively manufactured AlSi9Cu3Fe alloy is reported in this paper. Conventionally, the AlSi9Cu3(Fe) alloy is prepared by high-pressure die casting (HPDC), but this technology largely does not offer such opportunities as additive manufacturing (AM) does, especially in the design of new lightweight parts. In the present paper, testing samples were prepared by selective laser melting (SLM), one of the AM technologies, and characterized in terms of their microstructure (by means of light microscopy, scanning electron microscopy and transmission electron microscopy in combination with analytical techniques for evaluation of chemical and phase composition) and mechanical properties (static tension, compression, and hardness). All the characteristics were compared with the HPDC reference material. Our study showed an excellent improvement both in strength (374 +/- 11 MPa compared to 257 +/- 17 MPa) and plasticity (1.9 +/- 0.2% compared to 1.2 +/- 0.5%) of the material thanks to its very fine and distinctive microstructure.
