Alloy element carbon was added into a lamellar γ-TiAl alloy with a composition of Ti-47Al-
2Nb-2Cr. The volume fraction of B2 phase decreased with the increase of carbon content …

Abstract A Ti–48Al–2Cr–2Nb alloy with uniformly dispersed nano-Y 2 O 3 addition was
prepared by selective electron beam melting. The effects of beam speed on the defects …

TiAl-based alloys with high melting point become the promising high temperature structural
materials, but the inherent brittleness drawback suppresses their application. Here, we …

The effect of carbon addition on the high-temperature tensile properties and microstructure
of Ti-43Al-6Nb-1Mo-1Cr alloys has been studied in this paper. 0.5 at.% C could increase …
