Abstract

This freshman honors project has focused on the investigation of two unexplored binary titanium systems, Ti–Ca and Ti–Mg. The motivation of this project is to assess the possible production of materials for which there may be biomedical applications. The objective is to produce a metal-metal composite that can mimic bone and provide better elastic properties. This project used a Gleeble 3800 system to infiltrate a titanium architecture (i.e., skeleton) with calcium or magnesium at high temperatures. Using the Gleeble, separate specimens of Ti-Ca and Ti-Mg were produced by resistively heating both metals until calcium and magnesium were molten, allowing for a titanium architecture to be infiltrated by the molten metals. Following the sample preparation, the new composites were characterized using a scanning electron microscope and an x-ray diffraction spectrometer. The scanning electron microscope was used to observe the microstructure produced in the specimens and to analyze any compositional changes that occurred. The x-ray diffraction spectrometer was used to analyze the crystallographic phases produced in the specimen.
