Blades for use in combusion turbine engines are formed from a single crystal aluminum garnet body--desirably a rare earth aluminum garnet body--having an epitaxial surface layer of a second aluminum garnet having a lattice constant larger than that of the body garnet so as to provide a compressive strain, to thereby strengthen the blade.
