From crack-prone to crack-free: Eliminating cracks in additively manufactured Ti-48Al-2Cr-2Nb alloy by adjusting phase composition
At present, it remains a challenge to additively manufacture Ti-48Al-2Cr-2Nb (TiAl4822) alloy by laser powder bed fusion (LPBF) technology because of the severe cracking in the building process. In this work, it was found that cracks in LPBFed TiAl4822 alloy were more likely to occur in the region n...
