Microstructural and mechanisms of cyclic deformation of aluminum single crystals

Creator:

Delos-Reyes, Michael A.

Abstract:

Aluminum single crystals were cyclically deformed in single-slip at small strain amplitudes at 77 K to presaturation. The observed mechanical behavior is consistent with other recent work. The dislocation substructure was analyzed in detail. The structure can be described as consisting of dense bundles or veins of dislocation dipoles, separated...

Characterization of TiNbHf alloys for potential medical dental applications

Creator:

Amick, Darryl D.

Abstract:

A series of TiNbHf alloys ranging from 0-40 atomic % Nb and 0-15 atomic % Hf were evaluated to investigate low-elastic modulus phenomena which occur in this ternary system. The desirability of utilizing corrosion-resistant, biocompatible alloys with elastic modulus values approaching that of human bone for medical prosthetic implants provides...
