A Study of Dilute Aluminum and Vanadium Nmr in Alpha-Titanium and in Hydrogen Doped Alpha-Titanium (Knight Shift, Electron Distribution, Quadrupole Interaction, Anisotropic, Alloy(hcp))

Nuclear magnetic resonance was used to investigate Ti-1 at.% V, Ti-2 at.% V, Ti-1 at.% Al, Ti-2 at.% Al and in addition samples of these alloys containing 1 and 2 at.% H. Computer simulation of the absorption curves incorporates the effects of nuclear quadrupole and anisotropic shift interactions, dipolar broadening, and inhomogeneous Knight shift distribution. From the simulation work, experimental parameters such as electric field gradient (EFG), axial anisotropic Knight shift K(,ax), and isotropic Knight shift are obtained. In addition to shedding light on certain features of bonding of V and Al in Ti, this information is used to discuss the trapping of hydrogen in these systems.
