Abstract: PURPOSE: To provide a Cu-based amorphous alloy which increases amorphization efficiency, offers a possibility of application as structural material for copper alloy due to great increase of strength and is commercialized more easily by adding a fifth element to a conventional Cu-Ni-Zr-Ti quaternary amorphous alloy, thereby improving glass forming ability. CONSTITUTION: The Cu-based amorphous alloy composition is characterized in that it is represented as a general formula: $û(Cu+Ni)x(Ti+Zr)y$ý100-(a+b)(M1,M2)a(M3)b, wherein x, y, a and b satisfy 39

Abstract: PURPOSE: An amorphous alloy improved in amorphous formability obtained by adding Ag, Ni or Zn to conventional Mg alloy compositions comprising Mg, Cu and Y is provided, which can be used as amorphous light-weight material. CONSTITUTION: The titled alloy is obtained by adding below 25 atomic weight of one or more elements selected from the group consisting of Ag, Ni and Zn to magnesium alloy containing Cu and Y. The alloy can be processed to bulk materials by metallic mold casting at a cooling speed of several tens K/sec or less.
