Microstructure and Mechanical Properties of Ti-6Al-4V In Situ Alloyed with 3 wt% Cr by Laser Powder Bed Fusion
Abstract
This work studied the microstructure and mechanical properties of Ti-6Al-4V in situ<br/>alloyed with 3 wt% Cr by laser powder bed fusion (LPBF). Specimens with a relative density of<br/>99.14 ± 0.11% were produced, showing keyhole and lack of fusion pores. Due to incomplete mixing<br/>of the components during melting, chemical inhomogeneities were observed in the solidified material.<br/>The addition of Cr promoted thermal supercooling during solidification and induced a reduction in<br/>the primary β grain size in the longitudinal direction and a weakening of the otherwise strong ⟨100⟩β<br/>texture, both typical issues for Ti-6Al-4V produced by LPBF. The primary β at first transformed<br/>martensitically to α’, but by preheating the substrate plate to 500 ◦C and cyclically reheating the<br/>material by melting subsequent layers, in situ martensite decomposition was achieved, resulting<br/>in a fine lamellar α + β microstructure. In addition, the B19 phase was detected in the β matrix,<br/>presumably caused by Fe impurities in the Cr powder feedstock. Specimens exhibited a hardness of<br/>402 ± 18 HV10, and an excellent ultimate tensile strength of 1450 ± 22 MPa at an elongation at break<br/>of 4.5 ± 0.2%.
