The utilization of Edge-defined, Film-fed Growth (EFG) technique is proposed to produce continuous A1203-Y3A15012 (YAG) {NOTE: subscript the 2,3,3,5,&12} Eutectic fibers. The proposed program will proceed as follows: 1) optimize processing conditions for growing continuous alumina-YAG eutectic fibers using a commercial vendor's equipment, 2) construct an automated state-of-the-art continuous fiber growth apparatus, 3) use the apparatus built to produce large quantities of fiber and measure the mechanical properties of these fibers, and 4) establish the processing-microstructure-property relationship of the eutectic fibers.
