Gamma titanium aluminides are intermetallic alloys with great potential for aerospace
applications in low pressure turbines (LPT) because they can provide increased thrust-to-
weight ratios and improved efficiency under aggressive environments at temperatures up to
750 C. Due to that, γ-TiAl alloys are projected to replace the heavier Ni-base superalloys
currently used for LPT blades manufacturing. The objective of this research work is to study
the deformation and fracture mechanisms of a γ-TiAl alloy, Ti-45Al-2Nb-2Mn (at.%)+ 0.8 …
