Abstract
Incomplete recrystallization annealing treatment was carried out on hot-rolled TA18 sheet,and inhomogeneous microstructure with the characteristics of soft and hard phases was successfully obtained. Subsequently,lamellar TA18 titanium alloy with high strength and plasticity was fabricated through cold-rolling at room temperature,and the microstructure and mechanical properties of alloy were explored. The results indicate that the specimen with a thickness of 2.4 mm exhibits desirable performance after 700 ℃ ×3 h annealing + cold rolling treatment,where the tensile strength is 891 MPa and elongation reaches up to 15.6%. Therefore,the lamellar structure effectively retains the excellent plasticity specific to the recrystallized microstructure,leading to excellent strength and plasticity.
