Structure and properties of SLM-manufactured Ti-6Al-4V parts subjected to combined ultrasonic impact – Electrophysical treatment.

The paper deals with the effect of ultrasonic impact post-build processing combined with the electrophysical treatment of SLM-manufactured Ti-6Al-4V parts. Selectively laser melted blanks were cut along building direction and subjected to the combined treatment. Both as-received and the treated specimens were investigated using X-ray computer tomography and optical microscopy. Mechanical properties were evaluated under uniaxial tensile tests. The analysis of the experimental data had revealed the effect of post-build treatment on mechanical properties: ultimate tensile strength and elongation at break increased up to 5 % and up to 50 % correspondingly.
