NOVELTY - Spark plasma sintering (SPS) titanium-aluminum-tin-zirconium-niobium-molybdenum-silicon-graphene nanoparticles composite material (I) is new. USE - Used as spark plasma sintering titanium-aluminum-tin-zirconium-niobium-molybdenum-silicon-graphene nanoparticles composite material. ADVANTAGE - The material has excellent performance, and improved composition uniformity and oxidation resistance. DETAILED DESCRIPTION - Spark plasma sintering (SPS) titanium-aluminum-tin-zirconium-niobium-molybdenum-silicon-graphene nanoparticles composite material of formula (Ti-6Al-4Sn-9Zr-1.21Nb-1.6Mo-0.3SixGNP) (I) is new. The composite material is prepared by composite sintering of titanium-aluminum-tin-zirconium-niobium-molybdenum-silicon powder of formula (Ti-6Al-4Sn-9Zr-1.21Nb-1.6Mo-0.3Si) powder and nano-graphene powder, where the Ti-6Al-4Sn-9Zr-1.21Nb-1.6Mo-0.3Si-xGNP in Ti-6Al-4Sn-9Zr-1.21Nb-1.6Mo-0.3Si takes 30 g as equivalent unit, each equivalent unit of Ti-6Al-4Sn-9Zr-1.21Nb-1.6Mo-0.3Si needs to add x wt.% equivalent of nano GNP powder and the gradient is 1. x = 1-4. An INDEPENDENT CLAIM is also included for preparing composite material (I), comprising (i) placing certain quantity of graphene (GNP) into a ball milling tank, then adding certain amount of absolute ethanol into ball mill with a certain ball-to-material ratio, speed, ball milling time and ball milling interval so that the GNP powder is fully disperses, then pouring the prepared titanium-aluminum-tin-zirconium-niobium-molybdenum-silicon powder into the ball milling tank, mixing ball milled powder with just mixed graphene-ethanol solution, mixing titanium-aluminum-tin-zirconium-niobium-molybdenum-silicon powder and nano graphene nanoplatelets powder, performing ball milling, taking out the mixed powder, placing the mixed powder in a vacuum drying oven to keep warm and dry, performing dry grinding, passing dry-grinded powder into 300 mesh sieve, and then placing in a vacuum drying oven for drying, and (ii) pouring the mixed powder into graphite mold, and performing discharge plasma sintering in a sintering furnace to obtain final product.
