Definitions

  • the first aspect of the present invention relates to a process for producing an amorphous alloy material consisting of a principal element and additive elements and containing fine grains of perfect crystals having an average particle size of 2 to 100 nm that are formed by selfcontrol and dispersed in an amorphous alloy and to Ni-based amorphous alloys matrix.
  • Another one is an amorphous alloy material having high a toughness and strength and consisting of 80 to 90 atomic % of Mg as the principal element; and,as the additive elements, 1 to 5 atomic % of at least one element selected from among rare earth elements including Y and misch metal (Mm) and 8 to 15 atomic % of at least one other element selected from among Cu, Ni, Sn and Zn.
  • Mg amorphous alloy material
  • Mg may be replaced in part by at least one element selected from among Al, Si and Ca in the range of 1 to 5 atomic %.
  • the discharge of the solute from the crystal grains increases the solute concentration in the amorphous phase which surrounds the crystal grains, thus raising the crystallization temperature of the amorphous phase.
  • the amorphous phase is thermally stabilized.
  • the crystalline grains are inhibited in their growth and made into a substantially spherical form having a uniform partial size, which is regulated to 2 to 100 nm depending on the alloy species and treatment temperature.
  • the alloys produced according to the present invention are those in which a supersaturated solid solution composed of a principal element containing supersaturated additive elements precipitates at a temperature lower than the precipitation temperature of the intermetallic compounds or other compounds.
  • An FCC phase (Al phase) precipitates in an Al-based amorphous alloy, an HCP phase (Mg phase) in an Mg-based amorphous alloy and an FCC phase (Ni phase) in an Ni-based amorphous alloy.
  • the additive elements must be limited to a relatively low concentration, since an increased content of the additive elements causes the intermetallic compounds or other compounds to precipitate preferentially or simultaneously, thereby markedly embrittling the alloy and limiting the use thereof as an industrial material.
  • the FCC phase is grown to about 140 nm in crystal size at 580 K. It may be presumed that some intermetallic compounds have precipitated in the amorphous phase existing around the FCC phase to cause a decrease in the concentration of the solute in the amorphous phase and grow the FCC grains or that the sum total of the interfacial energy between the two phases has participated in such growth.
  • the alteration in the lattice constant of the FCC phase due to heating is given in FIG. 4. As seen from the figure, the crystal lattice constant of the FCC phase approaches the lattice constant of pure Al. The above fact is thought to result from the discharge of the solute from the FCC phase.
