Abstract: Methods are described for attaching ceramic fibrous bodies to metallic substrates. Metal fibers or metal wires are woven into the ceramic fibrous body which is to be adjacent the substrate and the exposed portion of these fibers or wires is attached by brazing to the substrate.

Abstract: Process for improving the crack growth behavior of titanium alloys containing substantial beta stabilizers and at least 3% molybdenum, such as Ti-6-2-4-6. The process includes the steps of forging above the beta transus temperature, cooling at a controlled rate through the beta transus temperature, heating to a temperature between 50.degree.-150.degree. F. below the beta transus temperature, cooling the alloy at a rate in excess of that produced by air cooling, and aging the material between about 900.degree. F. and 1100.degree. F. The resultant material has substantially improved crack growth behavior when contrasted with material processed according to the prior art.

Abstract: High modulus turbine shafts are described as are the process parameters for producing these shafts. The shafts have a high modulus as a result of having high <111> texture in the axial direction. The shafts are produced from a nickel base material having a strengthening phase and a moderate to high stacking fault energy. A combination of hot axisymmetric deformation followed by cold axisymmetric deformation produces an intense singular <111> texture and results in shaft material whose modulus is on the order of 25% greater than that of the steel materials used in the prior art.
