Abstract:
A method for the fabrication of a target useful in the production of quasicrystalline alloy thin films comprising:A) blending powders of the individual elemental constituents of the quasicrystalline alloy to form a powder blend; B) placing the powder blend into a vacuum press; C) evacuating the vacuum press or flooding the vacuum press with inert gas or a mixture of inert gas and from about 1 to about 5 percent by volume of hydrogen; D) heating the powder blend in the vacuum press to a temperature of between about 250Â° C. to about 500Â° C. to form a heated powder blend; and E) applying pressure of between about 2500 psi and about 20,000 psi to the heated powder blend for a period of at least two hours.
