Definitions

  • the mean particle size of particles of the intermetallic compound is the mean particle size of particles of a stable phase or a metastable phase of various intermetallic compounds formed from the above-described matrix element and other alloying elements and/or various intermetallic compounds formed from other alloying elements themselves.
  • the mean particle size is limited to 10 to 800 nm because when it is outside this range, the intermetallic compounds do not function as strengthening elements for the main metal element matrix. Specifically, when the mean particle size is less than 10 nm, the intermetallic compounds do not contribute to strengthening of the matrix. In this case, when the intermetallic compounds are excessively dissolved in the solid solution form in the matrix, there is a possibility that the material might become brittle. On the other hand, when the mean particle size exceeds 800 nm, the particle size becomes so large that the strength cannot be maintained and, at the same time, the intermetallic compounds do not function as strengthening elements.
  • preferred examples of the dispersed Al-M type compound include Al 3 Ni and Al 9 CO 2 and preferred examples of the Al-X type compound include Ce 3 Al 11 , Al 4 Ce, La 3 Al 11 , Mm 3 Al 11 , Al 3 Ti and Al 3 Zr.
  • a compound of a metastable phase has a higher effect of contribution to a fine dispersion.
  • the strength at room temperature and the strength at a high temperature of 200°C rapidly increased when the volume fraction of the Al 3 Ni intermetallic compound particles exceeded 17% and rapidly lowered when the volume fraction exceeded 29%.
  • Extruded materials consisting of various ingredients specified in Table 1 were prepared in the same manner as that of Example 1 to examine the mechanical properties (tensile strength) of these materials at room temperature.
  • mechanical properties tensile strength
