Microstructure and Mechanical Behavior of In-Situ Ti-TiB Whisker Composites

Abstract

This ARO-sponsored research was concerned with performing some pioneering work on synthesizing titanium-titanium boride composite materials by in situ reaction processes, modeling and evaluating their mechanical behavior. The research has demonstrated that low cost in situ titanium matrix composites with titanium boride whiskers can be made with properties comparable to some high strength steels. The research also has demonstrated that novel titanium boride coatings can be engineered on to the surface of titanium. Further, functionally graded material architectures based on gradation of titanium versus titanium boride have been made with the idea of demonstrating the feasibility of making graded armor material for ballistic applications. Comprehensive investigations mechanical behavior of these composites were conducted. New approaches were used in fracture mechanical modeling of layered and graded materials. The over all research work was novel in each of the areas highlighted above and has resulted in new technologies and approaches in titanium composite material synthesis and mechanical behavior modeling.
