Abstract: Multimodal cermet compositions comprise a multimodal grit distribution of the ceramic phase. The 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 a metal is a Group IV, V, or Vl metal, and wherein the metal binder phase comprises (i) Fe, Ni, Co or Mn and (ii) Cr, Al, Si, Y or Ti. The method of making multimodal boride cermets includes mixing multimodal ceramic phase particles, pressing the particle, liquid phase sintering of the compresses mixture at elevated temperatures, and finally cooling the multimodal cermet composition. Advantages of the multimodal cermets are high packing density, high fracture toughness and improved erosion resistance at up to 100 deg C. The multimodal cermets are suitable in high temperature erosion/corrosion chemical and petroleum environments.

Abstract: 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.
