- W2378618949 abstract "Nanocrystalline tungsten carbide(nano-WC) powder is prepared on the basis of the industrialized production equipment.Methods of X-ray diffraction,specific surface area,SEM,FESEM and TEM are applied to test the phase,particle size and its distribution of nano-WC powder.The results indicate the average particle size of nano-WC is about 90nm and most of the particles are spherical shape.Nano-WC powder is annealed at different temperatures for different time.The grain coarsening mechanism is studied and proved to be according with the classic LSW theory. Furthermore,temperature is an important factor to affect the grain growth of nano-WC and the grain size increases with the high temperature." @default.
