Abstract
Reinforcement fibers are formed from a single crystal garnet body--suitably an aluminum garnet, desirably a rare earth aluminum garnet--having an epitaxial surface layer of a second garnet having a lattice constant larger than that of the body garnet so as to provide a compressive strain, to thereby strengthen the fiber.
