| مستخلص: | During a projectile penetrating an armor, the material undergoes finite plastic deformation at high strain rates and temperatures, as well as at high hydrostatic pressures. US Army is contemplating on making a light tank using electron beam single melt titanium alloy as one of the metallic components. The manufacturing process of electron beam single melt results in a more economical version of the titanium alloy than the conventional alloy used in the aerospace application. Thus in this comprehensive study, quasi-static and dynamic uniaxial and multiaxial experimental results on electron beam single melt titanium alloys and one extra low interstitial (ELI) grade (for comparison) are presented, over low to high strain rates and temperatures, as well as under confining hydrostatic pressures. These experiments include compression, tension and torsion, as well as strain-rate jump experiments, in rolling (RD), transverse to rolling (TD) and thicknoess (ND) directions to quantify anisotropy of the plate material. Failure strains at different strain rates and different temperatures, in tension, compression and shear loading are also given. Microstructure is measured using an optical microscope and SEM. Material constants are determined for Johnson-Cook (J-C) & Khan-Huang-Liang (KHL) models, and observations are correlated with these models. Anisotropy in the material is fully characterized. Response of the material under confining pressures is also determined. The original document contains color images. |
