摘要

To study the dynamic behavior and microstructural evolution in high strain rate deformation of Ti-5Al-5Mo-5V-1Cr-1Fe (Ti-55511) alloy, a series of forced shear tests of hat shaped specimens have been conducted using a split Hopkinson pressure bar combined with “strain frozen” technique. Localized shear band is induced in these tests. This paper indicates that the flow stress of Ti-55511 alloy is independent on the punching depth, and thermal softening has a minor effect on the onset of adiabatic shear band and dynamic recrystallization formation. The concept of “adhesive fracture” can be identified as the dynamic failure mechanism for Ti-55511 alloy based on the crack propagation path.
