“…Titanium alloys are widely used in ships, armaments and aerospace because of their low density, high specific strength, high temperature and corrosion resistance and other excellent properties [1][2][3][4]. With the development of the marine sector and in-depth exploration of marine resources, the service conditions of materials for marine structural components are becoming more severe.…”

The titanium alloy has been used for marine structrural components because of the excellent properties. The response of material under explosion when in the service process should be carried out. In this research, the explosion test of the Ti6321 titanium of three different structure is executed to study the microstructure evolution. The optical microscope is used for observing the microstructure and adiabatic shear bands (ASB). The electron backscatter diffraction method is used to study the microstructure and recrystallization of the biamodal structural target under different charges. The result shows that the deformation of the target become larger with the increase of the charge. The ASBs have been observed in the target, demonstrating that it is an important reason for the damage. The twinning mechanism comes into play a role in the deformation of the material while dislocations become difficult to satisfy. The grain size of the bimodal material decrease with the increase of the charge. The deformed grains of the target start to recover and recrystallize at high temperature due to shock waves of explosion.

“…However, the efforts aimed to study the β phase change under high strain rates dominate, and there are few investigations on the change in the α phase under high strain rates in α or α + β titanium alloys. Yan et al [27] studied the deformation mechanisms of Ti6321 with duplex structure at different strain rates from 10 −3 s −1 to 10 5 s −1 , revealing that dislocation slip cannot well accommodate the plastic deformation at the strain rate of 10 5 s −1 , and {1212} <1011> tensile twins have been found as a large number of parallel twins.…”

The microstructure evolution of the twin of TB6 (Ti-10V-2Fe-3Al) under planar wave detonation was studied. The initial microstructure of the alloy consists of an α and β phase. It is found that twin deformation is operated in only the α phase due to the limited slip system in this phase. α grains are mainly rotated from {101¯0} to {0002} during the deformation due to the {101¯2}<101¯1¯> twin. Twin variant selection is found in this study, and the orientation of all {101¯2} twins is oriented at {0002} in different α grains with different deformation degrees. The twin variant selection is well explained based on the strain relaxation along the loading axis and the Schmid factor for twinning shear.

“…One method used to characterize the behavior of materials subjected to dynamic tension is the Split Hopkinson Tensile Bar (SHTB) [1][2][3][4][5][6]. This corresponds to a modification of the Split Hopkinson Pressure Bar (SHPB) introduced by Kolsky [7], for which strain rates ranging from 10 2 to 10 3 s −1 can be achieved [8].…”

“…The stress, strain, and strain rate determined from the recorded waves provide an accurate measure of the material behavior [2]. This method has been improved over the years and recent advances allow specimen heating [6], a wide strain rate loading range [5], or combined tension-torsion or compression-torsion that is capable of loading a specimen with a torsional stress pulse synchronously at high strain rates [9]. The results of SHTB tests with notched specimens combined with numerical simulation on Abaqus also allow Chen et al [3] to determine the parameters of the Johnson-Cook damage law of a material in addition to the parameters of the flow law.…”

This paper presents a new dynamic tensile test based on the Taylor impact technique for application on metallic materials. The Taylor impact test is a well-known technique to characterize the behavior of metallic materials in compression because it allows us to reach very high strain rates (105s−1). In this dynamic tensile test, we launch a projectile with an initial velocity into a specially designed target in order to generate tensile deformation in its central area. In this paper, the geometry of a tensile target previously published in our laboratory was modified and optimized to achieve higher plastic strains and strain rates without reaching the critical state of target failure. Numerical simulations and experimental tests validate the new geometry. Experimental tests have been performed with this new geometry to show the gains allowed. Numerical simulations by finite elements on Abaqus show the equivalent plastic deformations and elongation of the two versions of the targets and the correlation of these results with the tests.
