Abstract:
Pore-free Ti3 and Cr3 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 Cr3 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
