Microcrack nucleation and its effect on the plastic deformation of FL γ-TiAl alloy

Microcracks and their effect on the plastic deformation of γ-TiAl alloy with fully lamellar microstructure (FL) at relatively low strain rate (1 × 10⁻⁵/s) has been investigated. It is found that a large number of...
