Effect of delayed quenching on microstructure and properties of TC4 titanium alloy for aerospace fasteners

doi:10.13251/j.issn.0254-6051.2023.12.022

Abstract

Abstract: TC4 titanium alloy wire was subjected to delayed solution treatment and delayed solution+aging treatment for different time, and the microstructure, tensile and shear properties of the specimen were tested. The effect of delayed quenching on the microstructure and properties of the TC4 titanium alloy wires was explored. The results show that with the increase of delayed quenching time, the content of primary α phase decreases gradually, β transformation phase increases gradually and grain size increases gradually after solution and solution aging treatment. Compared with solution treatment, there is a higher content of strengthening phase and a smaller grain size in the microstructure after solution aging treatment. Greater strength and toughness, less plasticity. With the increase of delayed quenching time, the strength and toughness values decrease, while the plasticity values increase. Under the experimental conditions, the effect of 10 s-delayed quenching on strength reduction is basically equivalent to the effect of aging treatment on strength increase.
