摘要

The influence of ultrasonic treatment on the microstructure and properties of Ti-6Al-4V titanium alloy during its wire-feed electron-beam additive manufacturing is demonstrated. The experiments show that an application of ultrasound during printing enables a modest improvement of tensile mechanical properties of the specimens. Furthermore, in the specimen cross-section the ultrasonic treatment stabilizes the microstructure and causes the formation of more uniform columnar grains. The transverse dimensions of these columnar grains decrease from 1.3–1.5 mm in the samples printed without applying the ultrasound to 1.0–1.1 mm in those printed with an ultrasonic treatment.
