Effect of Process Parameters on Quality of Ti-6Al-4V Multi-Layer Single Pass Wall during Direct Laser Deposition with Beam Oscillation

Abstract:

In this paper, the effect of process parameters on quality of fabricated wall, the phase composition, microhardness, and mechanical properties of the Ti-6Al-4V titanium sample, obtained by direct laser deposition, was considered. To determine the characteristics of the samples the X-ray diffraction, scanning electron microscopy, Vickers microhardness measurements, and uniaxial tensile tests were used. It is shown that the process parameters with the same speed, oscillation amplitude and peak value of heat flux have a similar wall thickness but different waviness with high mechanical properties.
