| Popis: | The microstructure and strength characteristics of the Ti–6Al–4V alloy prepared using the selective laser melting (SLM) method with different sample building geometry using an EOSINT M280 machine have been studied. It has been found that the hardness and elastic modulus (EIT) measured by the nanoindentation method depend on the sample built geometry. The sample that is built horizontally relative to the substrate has the highest hardness. The lowest hardness and elastic modulus (EIT) are observed in the sample grown at an angle of 30°. The residual internal tensile stresses and microstresses depending on the orientation of the sample relative to the built platform have been detected. |
