Crack resistance of α2|γ and γ|γ interfaces within a TiAl alloy determined by in situ nano-fracture experiments by Michael Burtscher, Simon Fellner, Christoph Gammer, Markus Alfreider, Daniel Kiener

“…This could be attributed to dislocation emissions and crack tip blunting within the γ phase. The notched γ lamella exhibited enhanced plastic deformation, as evidenced by higher conditional J integral values of 100 J/m2. …”
