摘　　要：钛合金在变形过程中容易产生晶粒的择优取向,形成织构,造成材料性能出现明显的各向异性。随着钛合金在航空航天以及海洋工程领域应用的扩展,钛合金的塑性加工方法也日益增多,织构的类型及特征也随之变化。因此,织构对钛合金的力学性能以及主要服役性能的影响受到广泛关注。本文主要综述了钛合金塑性加工过程中变形织构的形成和演化机制,及其对钛合金的力学性能、疲劳性能以及应力腐蚀行为等的影响规律,以期为钛合金的合理应用提供指导。Textures are usually formed due to the preferred orientation of grains during the deformation of titanium alloys,causing significant anisotropy of material properties. With the development of titanium applications in aerospace and marine engineering, new plastic deformation methods have been applied to titanium alloys, which leads to a change in the type and features of the textures. Therefore, the influences of textures on the mechanical and main service properties have attracted much attention. This article mainly reviews the formation mechanism and the evolution of textures during the plastic deformation processes and their impact on the mechanical property, fatigue property, stress corrosion cracking behaviors and so on, hoping to offer guidance for the proper utilization of titanium alloys.
