摘要： A method for welding and repairing cracks in metal parts is provided by subjecting the metal parts to be welded to friction stir welding and the cracks to be repaired to friction stir processing under conditions sufficient to provide a weld joint or crack repair having a preselected property or set of properties based upon the intended use of the weldment. The FSW and FSP methods are advantageous in joining and repairing metal structures and components in applications for natural gas transportation and storage, oil and gas well completion and production, and oil and gas refinery and chemical plants.

摘要： The use of friction stir and laser shock processing in oil & gas and/or petrochemical applications is provided by the present invention. The use includes subjecting friction stir weldments, fusion weldments, and other critical regions of ferrous and non-ferrous alloy components used in oil & gas and petrochemical applications to laser shock processing to create residual compressive stresses near the surface of the treated area. The residual compressive forces in the ferrous or non-ferrous components improve properties including, inter alia, surface strength, fatigue life, surface hardness, stress corrosion resistance, fatigue resistance, and environmental cracking resistance. Friction stir and laser shock processing find particular application in high strength pipelines, steel catenary risers, top tension risers, threaded components, liquefied natural gas containers, pressurized liquefied natural gas containers, deep water oil drill strings, riser/casing joints, and well-head equipment.

摘要： Multimodal cermet compositions comprising a multimodal grit distribution of the ceramic phase and method of making are provided by the present invention. The multimodal cermet compositions include a) a ceramic phase and b) a metal binder phase, wherein the ceramic phase is a metal boride with a multimodal distribution of particles, wherein at least one metal is selected from the group consisting of Group IV, Group V, Group VI elements of the Long Form of The Periodic Table of Elements and mixtures thereof, and wherein the metal binder phase comprises at least one first element selected from the group consisting of Fe, Ni, Co, Mn and mixtures thereof, and at least second element selected from the group consisting of Cr, Al, Si and Y, and Ti. The method of making multimodal boride cermets includes the steps of mixing multimodal ceramic phase particles and metal phase particles, milling the ceramic and metal phase particles, uniaxially and optionally isostatically pressing the particles, liquid phase sintering of the compressed mixture at elevated temperatures, and finally cooling the multimodal cermet composition. Advantages disclosed by the multimodal cermets are high packing density of the ceramic phase, high fracture toughness and improved erosion resistance at high temperatures up to 1000° C. The disclosed multimodal cermets are suitable in high temperature erosion/corrosion applications in various chemical and petroleum environments.
