摘要:
On at least one surface of a base metal plate (1) of an α-γ transforming Fe or Fe alloy, a metal layer (2) containing ferrite former is formed. Next, the base metal plate (1) and the metal layer (2) are heated to an A3 point of the Fe or the Fe alloy, whereby the ferrite former are diffused into the base metal plate (1) to form an alloy region (1b) in a ferrite phase in which an accumulation degree of {200} planes is 25% or more and an accumulation degree of {222} planes is 40% or less. Next, the base metal plate (1) is heated to a temperature higher than the A3 point of the Fe or the Fe alloy, whereby the accumulation degree of the {200} planes is increased and the accumulation degree of the {222} planes is decreased while the alloy region (11b) is maintained in the ferrite phase.
摘要:
A niobium-based superconductor is manufactured by establishing multiple niobium components (4) 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 (7), 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 surface treated steel product which is prepared by tin-based plating or aluminum-based plating and is excellent in the resistance to corrosion, characterized as containing an intermetallic compound comprising one or more Group IIa (alkaline earth metal) elements and one or more Group IVb elements in a tin-based plating layer or an aluminum-based plating layer thereof. In the case of the tin-based plating layer, the intermetallic compound is preferably present in a massive form having a longer diameter of 1 mu or more and a ratio of a shorter diameter to a longer diameter of 0.4 or more, and in the case of the aluminum-based plating layer, the intermetallic compound is preferably present in a massive form having a longer diameter of 10 mu or more and a ratio of a shorter diameter to a longer diameter of 0.4 or more.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung eines elektrisch leitfähigen metallischen Bands zur Fertigung von Steckkontaktelementen. Hierbei wird zunächst ein Ausgangsband (2) aus Kupfer oder einer Kupferlegierung, welches eine gegenüber seiner Enddicke (D E ) größere Anfangsdicke (D A ) aufweist, verzinnt. Anschließend erfolgt eine walzende Verformung des verzinnten Ausgangsbands (2) mit einer Reduzierung der Banddicke (D 1 ) bis zu einer Fertigungsdicke (D 2 ) unter gleichzeitiger Reduzierung der Dicke des Ausgangsbands (2).
