Abstract: A method for producing a reinforced composite material. A molten matrix metal is heated to a temperature substantially greater than the melting point of the matrix metal. The matrix metal is poured into a mold containing a mass of reinforcing material, and an oxide layer formed from said molten matrix metal is ruptured so that the molten matrix metal infiltrates the mass of reinforcing material.

Abstract: A method is disclosed for producing a reinforced composite material. A molten matrix metal is heated to a temperature substantially greater than the melting point of the matrix metal. The matrix metal is poured into a mold containing a mass of reincforcing material. The matrix metal is solidified.

Abstract: This invention relates to iron-base alloy compositions, nickel containing austenitic ferrous alloy compositions (especially low nickel compositions) and dopants added to low nickel austenitic alloys as a means of improving the elevated temperature oxidation resistance of the resultant material.

Abstract: A method of improving the elevated temperature oxidation resistance of non-iron base alloys, especially nickel and cobalt base alloys by the addition of dopants to the oxide scale formed on a broad range of non-iron base alloys such as wrought or cast nickel or cobalt base heat resistant alloys.

Abstract: The method disclosed herein involves the addition of small quantities of elements appearing for the most part in Groups IA, IIA and IIIB of the Periodic Table to the base alloy composition. These elements, as ions, enter into the protective oxide scale and modify predominantly anion and to a lesser extent cation transport through the oxide scale, greatly reducing the amount of oxidation observed due to elevated temperature exposure.

Abstract: An improved method of electroforming a metallic member to a ceramic member and joint formed thereby. The method of this invention involves axially pre-loading a ceramic material to be joined to a metal shaft with a force sufficient to place the ceramic component into a state of compression about equal in magnitude to the axially directed tensile stresses expected to be induced in the ceramic material during shrinkage of the metal member about the ceramic.Further, the compressive pre-load is applied to the ceramic member through materials suitable for absorbing shock waves which might be generated along the longitudinal axis of the ceramic material.

Abstract: An improved method of electromagnetic forming a ceramic member to the end of a metallic member by the utilization of a metal sleeve which fits over the ceramic-metal joint formed by the two pieces to be joined. The metal sleeve traps the ceramic and the metal pieces together in one electromagnetic forming operation.
