研究了高速冲击对时效Ti49Ni51合金显微组织、相变和力学性能的影响。撞击后沿撞击方向的转变行为和微观结构呈现区域化特征，包括撞击坑附近的变形区域（0-4 mm）和撞击坑远端的未变形区域（5-6 mm）。应力诱发马氏体是时效Ti49Ni51合金在高速冲击下变形区的主要变形机制。
The effects of a high-velocity impact on the microstructure, phase transformation and mechanical property of aged Ti49Ni51 alloy are investigated. The transformation behavior and microstructure along the impact direction after impact emerge with regionalization characteristics, including a deformed region near the crater (0–4 mm) and an un-deformed region of the distal crater (5–6 mm). Stress-induced martensite is the main deformation mechanism in the deforming region of aged Ti49Ni51 alloy under high-velocity impact.
