N2 - Metallic materials are frequently exposed to high strain rates and complex stress conditions. Research on dynamic mechanical behaviors of these materials is essential for engineering design and industrial applications. In this paper, the dynamic plastic and flow behaviors of TC17 alloy under compression/tension-torsion were studied. The initial yield behaviors of TC17 alloy under quasi-static and dynamic loadings were researched, and a dynamic asymmetric yield criterion (DAYC) proposed by Yang, Guo, and Li was used to characterize the initial yield behavior. According to the hardening properties under different stress states, a modified dynamic hardening law (MDHL) was proposed to fit the loading surface. The plastic flow directions under quasi-static and dynamic loadings of TC17 alloy were investigated. Results showed that the plastic potential function may conform with the associated flow rule (AFR). The yield properties, strain hardening law, and plastic flow rule of TC17 alloy were systematically investigated and successfully characterized by DAYC and MDHL.
