Growth of Titanium and Chromium Strengthened Sapphire Fibers.
Abstract
Pore-free Ti(+3) and Cr(+3) doped Al2O3 fibers were grown by the Arthur D. Little fiber growth process. The absence of surface and bulk defects in these fibers resulted in higher virgin and abraded room temperature strengths than comparable fibers produced by another process. Solution hardening by Cr(+3) doping resulted in improved high temperature tensile strengths. The high temperature strength increase with a Cr content, so further improvements are probable with higher doping levels. (Author)
