NOVELTY - The preparation of alloy powder based alkene involves mixing 11-16.5 %mass chromium, 7-21 %mass cobalt, 0.1-5.9 %mass tungsten, 2-6.5 %mass molybdenum, 2-4.35 %mass aluminum, 2.3-5.5 %mass titanium, 0.1-3.7 %mass niobium, 0.015-0.15 %mass carbon, 0.006-0.028 %mass boron, 0-0.06 %mass zirconium, 0-6 %mass tantalum, 0-0.75 %mass hafnium, 0.05-5.5 %mass graphene and remainder of nickel, stirring to obtain alloy powder, adding powder to graphene oxide solution, washing, drying to obtain graphene oxide/nickel-based alloy powder composites, vacuum degassing, densifying, and heat treating. USE - Preparation of high temperature nickel alloy powder based alkene (claimed). ADVANTAGE - The method enables preparation of high temperature nickel alloy powder based alkene with improved strength and increases the plasticity of alkene to 40%.
