摘要
Composite fibers of starting mixtures of aluminum, yttrium, and calcium oxides and fibrous composite materials consisting of these fibers and a molybdenum matrix are fabricated by internal crystallization. The structure, the strength, and the cracking resistance of the fibers are studied in the temperature range 20-1400 degrees C. Inductile components are shown to be used to form composite materials with quasi-plastic behavior, and their cracking resistance can be 20-25 MPa m(1/2).
