Abstract Details

2013, Master of Sciences (Engineering), Case Western Reserve University, Materials Science and Engineering.
This work seeks to characterize a series of Ti-Zr binary alloys and a ternary Ti-Zr-Be alloy as anode materials for electrolytic capacitors. Specifically, this work attempts to improve the electrical behavior by reducing leakage through anodically grown oxide film on binary alloys via microstructure modifications. It also examines creep of Ti25Zr38Be37 metallic glass for surface enhancement. A variety of mechanical and electrical properties were measured. Leakage current through the anodic dielectric was found to decrease with increasing zirconium content. Alloy treatments which produce concentration gradients (a, a+ß fields) increased dielectric leakage; treatments maintaining uniform composition (as cast, wrought) retain low dielectric leakage current. UTS was fit to a solid solution model which compares well with related literature. Estimates of viscosity for Ti25Zr38Be37 metallic glass were made at various temperatures and resulting surface texturing examined. Long term creep rate change was fit to exponential decay with a time constant of 7.9x103s.
