摘要	Strengthening abilities (Hall-Petch coefficients) and the barrier strength of alpha/beta lamellar interfaces and coarse primary/fine secondary alpha lamellae interfaces in Ti alloys are theoretically estimated based on the lattice and modulus mismatches of two phases on both sides of the interfaces. The results reveal that the strengthening abilities of the alpha/beta lamellar interfaces and the coarse primary/fine secondary alpha lamellae interfaces are about 272.6 and 68.9 MPa mu m, respectively, and the interface barrier strength of the alpha/beta lamellar interface is about 9.5 times higher than that of the coarse primary/fine secondary alpha lamellae interface. The variation trend of the interface strengthening abilities with the fraction of alpha/beta interfaces for lamellar Ti alloys is found. The finding may provide a potential strategy for enhancing the strength or deformability of lamellar Ti alloys through manipulating interface properties.
