Feasibility Study Of Fabricating A Partly Amorphous Copper-Rich Titanium Alloy Via In-Situ Alloying In Laser Powder Bed Fusion
Abstract
<p>Bulk metallic glass composites (BMGCs) overcome the unfavorable lack of plastic deformation of completely amorphous alloys by adding ductile metallic shares. This is the first study that attempts to produce a partially amorphous alloy in an inexpensive and straightforward system of Ti-6Al-4V - 15 wt.% Cu using laser powder bed fusion (LPBF) with in-situ alloying. Local chemical inhomogeneities are desired, as they allow simultaneous solidification of crystalline and composition-dependent amorphous areas. The influence of the scan strategy on microstructural features was investigated by applying single melting and pulsed remelting strategies. The remelting strategy led to the formation of an X-ray amorphous phase, causing grains < 1 µm to increase from 7.8 % (single melting) to 14 %, while at the same time, the number of pores and cracks decreased. This study shows the feasibility of producing a partly X-ray amorphous alloy in which the amount of X-ray amorphous shares can be controlled with process parameters.</p>
