Yttria Nano-Particle Reinforced CP Titanium

Literature shows that doubling of tensile properties is achievable via nano-sized yttria Y203 dispersion in titanium. These initial studies reported proof of concept using small laboratory-scale samples produced via arc-melting but further studies to establish the technology and applications are lacking. The objective of this work is to study the scale-up feasibility of yttria dispersed titanium and to investigate the influence of yttria nano particles on the tensile properties of titanium. The focus of this effort is to perform initial experiments to determine if this effect occurs in metal powder produced through gas atomization. In addition, a higher strength version of the material was sought through the addition of boron. This project is designed to explore the efficiency of nano-sized yttria at improving tensile properties of CP titanium for US Army applications. This phase of the project is focused on evaluating the tensile properties of a limited number of samples with specified compositions.
