Deformation-aging behavior and property evolution of Cu–Ti alloys prepared by accumulative roll bonding-deformation diffusion process

Herein, large electrical conductivity of 21% IACS and high strength of 1118 MPa in the Cu‐3.3 wt%Ti alloy are successfully achieved based on the coupling control of microalloying, deformation, and aging. It is revealed that compared with the Mg‐free Cu‐3.3 wt%Ti alloy prepared by traditional treatment methods, such as aging, deformation + aging, and the novel method of preaging + cold rolling + aging, both the addition of 0.1 wt%Mg and the novel method of preaging + cold rolling + aging not only can greatly improve the uniform distribution level of dislocation formed during cold rolling and reduce the average size of precipitates, but also can significantly improve the formation of multiscale precipitates with higher volume fraction and their coupling distribution with dislocations, which effectively improve the electrical conductivity and strengthening contribution of precipitates and dislocation simultaneously. The results shed light on the understanding of related mechanisms in Cu‐Ti alloys and hopefully also provide theoretical guidance for industrial production and applications of Cu‐Ti alloys with excellent properties.
