Mechanical Behavior of Titanium Alloys (Effects of Hydrogen on Anisotropic Elastic Properties of bcc Ti Alloys).

Abstract

The effects of hydrogen in solid solution on the anisotropic second order elastic constants of Ti-40V and their temperature coefficients have been determined. Using recently published pressure derivatives of hydrogen-free materials we were able to separate out intrinsic alloying effects (due to hydrogen doping) from those due to the accompanying lattice parameter change. The intrinsic effects, which are electronic in nature, are found to be positive and those due to the lattice parameter change are negative. Furthermore, it is shown that the anisotropy factor increases with increasing hydrogen concentration. Some implications of these observations are briefly discussed. (Author)
