A tiltable cooled crucible for containing the molten alloy has a spout for extracting the molten alloy. The alloy is cast on an advanceable chilled surface. The cooled crucible is protected from the molten alloy by a solidified layer of the alloy which is solidified and prevents reaction between the molten alloy and the cooled crucible.

Amorphous nickel, aluminum, and boron alloys are described. These alloys are characterized by high hardness and high crystallization temperatures.

Amorphous alloys of nickel, aluminum and boron

Zirconium alloys containing at least two of the transition metal elements of iron, cobalt and nickel are disclosed. The alloys consist essentially of at least two elements selected from the group consisting of about 1 to 27 atom percent iron, about 1 to 43 atom percent cobalt and about 1 to 42 atom percent nickel, balance essentially zirconium plus incidental impurities. The alloys in polycrystalline form are capable of being melted and rapidly quenched to the glassy state. Substantially totally glassy alloys of the invention evidence unusually high resistivities of over 200 .mu..OMEGA.-cm.

Amorphous metal alloys are prepared from titanium-beryllium base compositions comprising about 48 to 68 atom percent titanium and about 32 to 52 atom percent beryllium, with up to about 10 atom percent of beryllium replaced by additional alloying elements such as transition metals and metalloids. These alloys evidence high strength, good ductility and low density. The alloys are potentially useful in applications requiring a high strength-to-weight ratio.
