摘要： A method of and apparatus for fabricating clad ingots or clad slabs includes a hollow body which corresponds to the dimensions of a finished slab and which has at least one side plate of cladding material and other thinner side sheets forming an upright tubular hollow body which is inserted into a larger ingot mold. Refractory insulating material is disposed between the bottom end of the hollow body and the bottom wall of the mold and between the sides of the hollow body and the sides of the mold, the hollow body being subsequently charged with a molten base metal. Prior to inserting the hollow body into the mold, the bottom end thereof is sealed closed by a bottom wall and a cover plate is placed on the top end of the hollow body.

摘要： A method of producing layer-like clad metal materials is disclosed. The layer-like clad metal material is produced by applying an organic substance consisting mainly of carbon and hydrogen to the surface of a metallic core material having at its surface substantially no oxide film to form a coating film having a thickness of 50-3,000 .mu.m, placing said core material in a casting mold, pouring a molten metal having the same or different composition around said core material into said mold by a bottom pouring process to form a clad metal ingot, subjecting said ingot to slab rolling or forging to form an intermediate product, and then subjecting said intermediate product to a hot working and, if necessary, a cold working.

摘要： Composite billets that function as starting stock for superconducting wire are produced by immersing an assembly of rods of a superconductor alloy or rods of a metal which is capable of forming a superconductor into a molten bath of normal material, thereby encasing the assembly within normal material, allowing the molten bath to solidify and form a rough as-cast billet and thereafter zone-melting the billet so as to remove all vestiges of shrinkage cracks, surface imperfections and internal inhomogeneities.

摘要： A unitary composite metal article formed of two dissimilar metals and the process for making the same by heating a substrate metal to a bonding temperature which is below the melting point of both the substrate and the casting metal; bringing the heated substrate and the molten casting metal into contact in an article-forming mold in the absence of an oxidizing atmosphere until wetting and molecular adhesion at the interface has been attained; and establishing a rate of heat transfer between the molten casting metal and the solid substrate which will cause chilling and solidification of the casting metal at the interface before formation of an interfacial alloy can occur. The resulting composite article represents a molecular bond of the casting metal to the substrate at the interface and is free from any visible interfacial alloy stratum.
