Jedną z technik druku 3D, dzięki której można wytworzyć metodą przyrostową niemalże lite elementy metalowe, jest metoda laserowego przetapiania proszków SLM (ang. selective laser melting). Jest to nowoczesna technologia pozwalająca na tworzenie elementów, które znajdują zastosowanie w obszarach począwszy od przemysłu motoryzacyjnego i lotniczego, a skończywszy na przemyśle stomatologicznym czy medycznym [1-3].

One of the 3D printing technologies thanks to which almost solid metal elements can be produced using the additive method is SLM (selective laser melting). This is a modern technology that enables creating elements which are used in areas ranging from the automotive and aviation industry to the dental or medical industry [1-3].

This study investigated the impact of the equal channel angular pressing (ECAP) combined with heat treatments on the microstructure and mechanical properties of AlSi10Mg alloys fabricated via selective laser melting (SLM) and gravity casting. Special attention was directed towards determining the effect of post-fabrication heat treatments on the microstructural evolution of AlSi10Mg alloy fabricated using two different routes. Three initial alloy conditions were considered prior to ECAP deformation: (1) as-cast in solution treated (T4) condition, (2) SLM in T4 condition, (3) SLM subjected to low-temperature annealing. Light microscopy, transmission electron microscopy, X-ray diffraction line broadening analysis, and electron backscattered diffraction analysis were used to characterize the microstructures before and after ECAP. The results indicated that SLM followed by low-temperature annealing led to superior mechanical properties, relative to the two other conditions. Microscopic analyses revealed that the partial-cellular structure contributed to strong work hardening. This behavior enhanced the material’s strength because of the enhanced accumulation of geometrically necessary dislocations during ECAP deformation.
