摘要：
The present study compares two additive manufacturing methods, wire arc and electron beam ones, by analyzing the structural and mechanical characteristics of 3D printed Ti-Al-Zr-Mo-V alloy components. The macrostructure of the studied Ti-Al-Zr-Mo-V components is represented by columnar primary beta grains of the Widmanstatten pattern with lamellar alpha colonies of different sizes and orientation. During the electron beam additive manufacturing (EBAM) process, the concentration of the alpha-stabilizing Al decreases from 3.81 +/- 0.59 to 2.72 +/- 0.53 wt.%. However, during the wire arc additive manufacturing (WAAM) process, the Al concentration is kept within the error range. The components printed by the EBAM method show anisotropy of mechanical properties. The ultimate strength is 757-767 MPa for the EBAM-fabricated components and 887- 896 MPa for the WAAM-fabricated components.
