Abstract

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.
