      Shear-Compressive Loading Conditions.

AB  - Titanium Ti6Al4V alloy is a superior material that has extremely high strength, 
      hardness and good anti-corrosion resistance. Dynamic shear-compression 
      experiments were carried out on the alloy to investigate the micro-mechanisms of 
      adiabatic shear banding (ASB) formation. The split Hopkinson pressure bar (SHPB) 
      setup were used for the tests at high strain rates. It was found that the shear 
      deformation localization (SDL) was considerably affected by the complex loading 
      conditions. The micro-mechanisms for the ASB formation relied on different shear 
      compressive proportion of loadings (SCLPs). Scanning electron microscope (SEM) 
      observations showed that the ASB width was related with the SCLP and the fracture 
      failure of alloy was induced by the nucleation and growth of microvoids. In 
      transmission electron microscope (TEM) analysis, the microstructural changes of 
      material within the ASB were characterized by dynamic recrystallization (DRX) and 
      twining grain formation, dislocation migration, and stacking and grain refining 
      processes. The results in this article demonstrates a complex image of 
      microstructural evolution of alloy in the shear localization process.
