Study of NbSi composites reinforced by single-crystal fibers of α-Al2O3 with and without interfacial coating

详细

The interaction between the Nb–Si–Ti matrix and single-crystal α-Al₂O₃ fibers with and without the interfacial coating on interphase boundaries is studied: fiber–coating–matrix and fiber–matrix. It is established that at 1300°C the bending strength of the composite material reinforced by fibers without coating is 1.5 times higher than that of the matrix, and the bending strength of the material reinforced by fibers with coating is 2.5 times higher.
