Mechanical properties of composite materials produced with the use of Al–TiB₂ SHS powders by direct laser deposition

This paper presents a study of the mechanical properties of composite materials produced with the use of Al-TiB2 powders by direct laser deposition at different powder consumption. With an increase in the powder consumption, a decrease in the hardness and compressive strength of the composite materials is observed. Such a dependence is directly related to the porosity of the composite material, which increases with an expansion of the powder consumption during laser deposition. The use of Al-TiB2 powder as the main raw material during direct laser deposition with a powder consumption of 5.1 g/min allows the production of composites with the optimal hardness and compressive strength in the selected range of powder consumption variation. The obtained data exceed the characteristics of the traditional aluminum-based alloys.
