Popis: Reinforcing a molybdenum matrix with appropriate oxide fibers slows down oxidation of molybdenum at high temperatures. At the same time, oxide fibers crystallized from the melt determine high creep resistance of the composites at temperatures up to about 1300 °C. An analysis of the experimental data on creep rupture and matrix oxidation yields a general idea of tailoring creep resistant refractory metal matrix composites of high fracture toughness and sufficiently high gas corrosion resistance. To develop such composites, it is necessary to reinforce a refractory metal with creep resistant fibers containing an element providing gas corrosion resistance of the composite.
