    摘要： A method for supplying molten metal alloy for producing thin amorphous metal wire or thin amorphous metal strip by liquid quenching and solidification on a moving cooling substrate controls the flow of molten metal from a ladle into a tundish. The ladle has a long nozzle with an interior passage for providing flow of molten metal alloy into the tundish. The ladle stopper has a distal end region received by the interior passage of the long nozzle. Control of the overlap between the distal end region of the ladle stopper received in the long nozzle during molten alloy flow and control of the sectional flow area provided in the long nozzle interior passage controls the flow quantity of molten alloy from the ladle into the tundish.

    摘要： The present invention provides an Fe-based alloy foil for liquid phase diffusion bonding of Fe-based material by enabling bonding in oxidizing atmospheres at relatively high bonding temperatures to minimize thermal influence on the base material (the material to be bonded) and, thereby, ensures production of a bonded joint having a uniform microstructure and a good bonded joint strength and enables reduction in the bonding time. The Fe-based alloy foil contains, as essential elements, one of 1.0 to 20.0% P and 1.0 to 20.0% B, 1.0 to 20.0% Si, and 0.1 to 20.0% V, in terms of atomic percentage, the balance substantially of Fe and unavoidable impurities, and has a thickness of 3.0 to 100 .mu.m. Alternatively, the Fe-based alloy foil contains, as essential elements, 1.0 to 20.0% P, 1.0 to 20.0% Si, and 0.1 to 20.0% V, and 1.0 to 20.0% B, in terms of atomic percentage, the balance substantially of Fe and unavoidable impurities, and has a thickness of 3.0 to 200 .mu.m. In accordance with need, one or more of Cr, Ni and Co and/or one or more of W, Nb and Ti are also contained in suitable amounts. The foil advantageously has a substantially amorphous crystallographic structure.
