摘　　要：利用塑性势理论，同时通过各种复合应力试验证明了TA2钛管具有明显的各向异性和双向强化效应，并提供了钛管换热器合理设计的可靠依据．Under the different combinatory loads the thin titanium tube possesses different stress states. In particular, the anisotropy and biakial strengthening of TA2 titanium tube directly influences the reasonable design of the titanium tubular exchanger. Using the plastic potential theory and through different combinatory stress experiments, this paper proves the anisotropy and biaxial strengthening effect of TA2 titanium tube, and presents a reliable basis for the reasonable design of the titanium tubular exchanger.
