  • Process for producing titanium material for target, titanium material for target, and sputtering target using the same
    Patent number: 6984272
    Abstract: A titanium material for a target has a microstructure in which the grain size is small and uniform and also has a macrostructure of the surface of the titanium material which is non-patterned and is excellent in surface property. A titanium ingot in which Vacuum Arc Remelting or Electron Beam Melting is performed is roughly forged at a temperature from 700° C. up to the ? transformation temperature, and is then forged for finishing at room temperature to 350° C., and is finally annealed.
    Type: Grant
