摘要： The present disclosure provides a copper-phosphorus-tin brazing wire and a preparation method thereof, relates to the technical field of brazing materials. The copper-phosphorus-tin brazing wire is of a three-layer structure, the inner layer is Cu, the middle layer is Cu-14P alloy, and the outer layer is Sn, wherein the mass percentage of Sn is over 7%. The present disclosure solves the technical problems in the prior art that the copper-phosphorus-silver brazing filler metal is prone to produce defects such as pores and inclusions when brazing copper alloys, which leads to the decline of the mechanical properties of the joint, and simultaneously provides the preparation method of the copper-phosphorus-tin brazing wire, such that the technical problem that it is difficult to obtain copper-phosphorus-tin brazing wire with a wire diameter below 0.5 mm under the condition of high Sn content is solved.

摘要： A steel sheet for containers including a steel sheet, a Sn coated layer that is formed on at least one surface of the steel sheet, and a chemical treatment layer that is formed on the Sn coated layer. A variation amount in a yellowness index measured at one measurement point on the outermost surface of the chemical treatment layer is defined as ΔYI, and represented by ΔYI=YI−YI0, wherein YI is the yellowness index measured after the steel sheet for containers is subjected to a retort treatment at a temperature of 130° C. for 5 hours, and YI0 is the yellowness index measured before the retort treatment. An average of absolute values of the ΔYI obtained at a plurality of measurement points included in a unit area of the outermost surface is 5.0 or less.

摘要： A niobium-based superconductor is manufactured by establishing multiple niobium components in a billet of a ductile metal, working the composite billet through a series of reduction steps to form the niobium components into elongated elements, each niobium element having a thickness on the order of 1 to 25 microns, surrounding the billet prior to the last reduction step with a porous confining layer of an acid resistant metal, immersing the confined billet in an acid or a high temperature liquid metal to remove the ductile metal from between the niobium elements while the niobium elements remain confined by said porous layer, exposing the confined mass of niobium elements to a material capable of reacting with Nb to form a superconductor.

摘要： A process for tinning plated wire involves first the placing of the wire in a suitable chemical flux for a period of time, the wire is then immersed for a period of time into a static solder pot having molten solder therein, the wire is then re-immersed into the chemical flux for a period of time, and finally the wire is immersed for a period of time into an ultrasonic solder pot having molten solder therein, the wire when removed from the ultrasonic pot being sufficiently tinned such that the solder has formed a suitable intermolecular bond to the plating in accordance with typical bonding criteria.
