164 761, 164 691, 164462, 164423, 148513, 148561, 148403, 148422, 148423

Abstract:

A method of producing metal fibers including melting a mixture of at least a fiber metal and a matrix metal, cooling the mixture to form a bulk matrix comprising at least a fiber phase and a matrix phase and removing at least a substantial portion of the matrix phase from the fiber phase. Additionally, the method may include deforming the bulk matrix. In certain embodiments, the fiber metal may be at least one of niobium, a niobium alloy, tantalum and a tantalum alloy and the matrix metal may be at least one of copper and a copper alloy. The substantial portion of the matrix phase may be removed, in certain embodiments, by dissolving of the matrix phase in a suitable mineral acid, such as, but not limited to, nitric acid, sulfuric acid, hydrochloric acid and phosphoric acid.

Abstract:

According to one aspect of the present disclosure, a part for an article of equipment includes a fluid conducting first region including a corrosion resistant first material, and a fluid conducting second region including a second material. The first region and the second region are either directly or indirectly joined by solid state welding to form a unitary fluid conducting part. According to another aspect of the present disclosure, a method for replacing at least one fluid conducting part of an article of equipment is disclosed wherein a replacement part is provided that includes a fluid conducting first region including a corrosion resistant first material, and a fluid conducting second region including a second material. The second material is substantially identical to the material of a region of the equipment on which the replacement part is mounted. The first and second regions are either directly or indirectly joined by solid state welding to form a unitary fluid conducting replacement part.
