Abstract
The shock compressive wave profiles of commercial-purity titanium samples under different loading conditions have been measured. The spall strength of titanium as a function of the strain rate and temperature of deformation has been found. High-rate plastic deformation mechanisms have been studied. High-rate plastic deformation under the investigated loading conditions has been shown to occur by slip and twinning. The α → ω transformation has been established to begin at 12.2 GPa.
Highlights
A rather large number of works are devoted to the investigation of titanium behavior under shock loading [1,2,3,4,5,6,7,8,9,10,11,12]
According to the X-ray investigation of the phase composition of VT1-0 titanium, it consists of the α phase in its initial state
The diffraction peaks in the X-ray diffraction (XRD) patterns are quite narrow, indicating that there are no significant distortions in the structure
Summary
A rather large number of works are devoted to the investigation of titanium behavior under shock loading [1,2,3,4,5,6,7,8,9,10,11,12]. A major part of them deals with the investigation of the mechanisms of plastic deformation and fracture under plane shock-wave loading of commercial-purity VT1-0 titanium. Dynamic yield strength is less sensitive to material composition, structure, and test temperature than yield strength [1]. An increase in temperature from 20 to 600°C does not affect the resistance to high-rate plastic deformation [2]. An annealing-induced decrease in dislocation density reduces the hardness of the material, but increases its dynamic yield strength considerably [3]. High-rate deformation results in the formation of shear bands in the fracture region and adiabatic shear bands [4, 5]
