Compositions for forming Au-based bulk-solidifying amorphous alloys are provided. The Au-based bulk-solidifying amorphous alloys of the current invention are based on ternary AuCuSi alloys, and the extension of this ternary system to higher order alloys by the addition of one or more alloying elements. Additional substitute elements are also provided, which allow for the tailoring of the physical properties of the Au-base bulk-solidifying amorphous alloys of the current invention.

The present invention relates to a mirror having a backing plate or polymeric substrate being coated with a reflective coating, for example a chromium-based reflective coating. A mirror assembly includes a mirror housing, a reflective element having a first field of view, a reflective coating having a second field of view, the second field of view being wider than the first field of view, and a multi-function backing plate supported by the mirror housing and comprising a reflective element supporting region where the reflective element is supported by the multi-function backing plate and a reflective coating supporting region where the reflective coating is applied to the backing plate.

The copper alloy for electric and electronic device includes more than 2.0 mass % to 15.0 mass % of Zn; 0.10 mass % to 0.90 mass % of Sn; 0.05 mass % to less than 1.00 mass % of Ni; 0.001 mass % to less than 0.100 mass % of Fe; 0.005 mass % to 0.100 mass % of P; and a remainder comprising Cu and unavoidable impurities, in which 0.002Fe/Ni<1.500, 3.0<(Ni+Fe)/P<100.0, and 0.10<Sn/(Ni+Fe)<5.00 were satisfied by atomic ratio, and a yield ratio YS/TS is more than 90% which is calculated from a strength TS and a 0.2% yield strength YS when a tensile test is performed in a direction parallel to a rolling direction.

The invention relates to a method for producing packaging steel consisting of a cold-rolled steel sheet made of unalloyed or low-alloy steel having a carbon content of less than 0.1%. In order to provide high-strength packaging steel that has good formability and high corrosion resistance and can be produced in as energy-saving a manner as possible, the steel sheet according to the invention is first coated with a metallic coating and then annealed in a recrystallizing manner at a heating rate of more than 75 K/s and preferably more than 100 K/s to temperatures of more than 700 C., such that the metallic coating melts. The coated and annealed steel sheet is then quenched to normal temperature at a cooling rate of at least 100 K/s.
