YAP-Based Fibers Obtained by Internal Crystallization Method

Two new types of oxide fibers, namely, those of single crystalline yttrium-aluminum perovskite YAlO 3 (YAP) and two-phase YAlO 3-Y 4Al 2O 9 (YAP-YAM), have been grown by the internal crystallization method. The fibers of the second type retain their strength at temperatures up to 1000 °C. Their effective strength in a molybdenum matrix reaches about 600 MPa at a temperature of 1400 °C. View Full-Tex
