Abstract

Abstract: Effect of different cold deformations on microstructure and mechanical properties of TC4 alloy and effect of the recrystallization treatment on the degree of recrystallization of the alloy with different cold deformations were investigated by means of XRD, OM, EDS, SEM and universal testing machine. The results show that cold rolling makes TC4 alloy work harden, and the tensile strength of the specimens with 35% and 48% cold deformation increases by 451 MPa and 228 MPa than the solution specimens, respectively. Under the conditions of the same recrystallization process, it is found that as the deformation increases, the tensile strength of the alloy gradually decreases.

Key words: TC4 alloy, cold rolling, deformation, recrystallization
