    摘要： Disclosed is a Fe-based bulk amorphous alloy composition which forms a bulk amorphous substance due to its excellent amorphous formability when it is cooled to a temperature lower than its glass transition temperature from the liquid state at a relatively low cooling rate of 1000 K/s or less, has high warm processability in a low temperature range owing to its supercooled liquid region of 20K or higher and has excellent fluidity in the liquid state and thereby good castability. The Fe-based multi-element bulk amorphous alloy composition is represented by a formula of Feα, CβSiγBxPyMa, in which M is at least one element selected from Ti (titanium), Cr (chromium), Mo (molybdenum), Nb (niobium), Zr (Zirconium), Ta (tantalum), W (tungsten) and V (vanadium), α, β, γ, x, y, and a each represent atomic % of iron (Fe), Carbon (C), silicon (Si), boron (B), phosphorus (P) and the selected metal element, in which α is 100-(β+γ+x+y+a) atomic %, β is 6 atomic % or more and 13 atomic % or less, γ is 1 atomic % or more and 5 atomic % or less, x is 4.5 atomic % or more and 9.5 atomic % or less, y is 3 atomic % or more and 10 atomic % or less and a is 0.1 atomic % or more and 6 atomic % or less.

    摘要： Disclosed is a quasicrystalline phase-reinforced Mg-based metallic alloy with high warm and hot formability, and making method thereof. The metallic alloy comprises a composition of Mg—1˜10 at % Zn—0.1˜3 at % Y, in which a two-phase region consisting of a quascrystalline phase and a magnesium-based solid solution phase exists. Constituting a matrix structure, the Mg-based solid solution phase (&agr;—Mg) is formed as a primary solid phase upon solidification. The quasicrystalline phase serves as a second phase and forms, together with the Mg-based solid solution phase, a eutectic phase, thereby reinforcing the matrix. The materials obtained through the hot rolling or extrusion of the cast alloy have an increased volume % of the second phase and thus show significantly increased strength.
