摘要： A NiTi-based tube of memory metal is produced by extrusion, whereby: a) one starts off from a blank of a memory metal; b) a central hole is drilled in said blank; c) a core is introduced into the central hole, whereafter the blank is encased by a casing, and preferably also by two gables, whereby the blank is excluded from the surrounding atmosphere; d) the encased blank is heated and extruded; e) the ends of the extruded blank are removed; and f) also the core and the surrounding casing is removed. In this way, it has been accomplished to produce NiTi-based tubes of memory metal of hitherto unattained length, such as » 1/2 m.

摘要： On prépare un alliage supraconducteur de type II, lequel est supraconducteur à un champ magnétique élevé prédéterminé, en produisant un composite présentant un agencement périodique d'au moins deux métaux de transition de façon à obtenir de nombreuses interfaces entre les différents métaux de transition, lesquels comprennent le niobium, le titane, le zirconium, le vanadium, le hafnium, le tantale ainsi que des alliages de ceux-ci. La combinaison de métaux de transition est choisie de telle façon que l'un des métaux agit comme une seconde phase lorsque les couches sont soumises à des températures susceptibles de produire un état d'équilibre à deux phases à partir d'un alliage en solution solide des métaux de transition. Le composite est mécaniquement réduit et chauffé de façon à produire une diffusion réciproque des métaux de transition pour former des zones d'alliage supraconducteur ductile au niveau des interfaces des métaux de transition. Un traitement thermique suffisant est effectué dans la région où deux phases sont présentes dans le diagramme d'équilibre, de façon à produire une région à deux phases, l'une des phases étant composée de l'alliage supraconducteur de type II requis et l'autre de l'alliage ou du métal normal non supraconducteur. La température de traitement thermique est limitée à la région à deux phases. Le composite subit ultérieurement une réduction mécanique, de sorte que les deux zones présentent chacune une épaisseur inférieure à 1000 nm environ.

摘要： A type II superconducting alloy which is superconducting at a predetermined high magnetic field is prepared by creating a composite having a periodic arrangement of at least two transition metals so as to provide numerous interfaces between the different transition metals including niobium, titanium, zirconium, vanadium, hafnium, and tantalum, and alloys thereof. The combination of transition metals is such that one of the metals will serve as a second phase when the layers are subjected to temperatures which would produce a two-phase equilibrium state from a solid solution alloy of the transition metals. The composite is mechanically reduced and heated to cause interdiffusion of the transition metals to form ductile superconducting alloy zones at the interfaces of the transition metals. Sufficient heat treatment is provided in the region where two phases exist in the phase diagram to form two phases, one phase being the desired superconducting Type II alloy and the other phase being the non-superconducting normal metal or alloy. The temperature of heat treatment is limited to the two-phase region. Thereafter, the composite is mechanically reduced so that the two zones are each less than about 1,000 nm in thickness.

摘要： A method for producing a superconductor by partial inter diffusion of layers of metal under a diffusion heat treatment to provide a ductile beta phase alloy, along with undiffused metal layers to permit ease of extrusion and drawing to fine layer thickness. At some point in the reduction the layers are further diffused to give an alloy superconducting product which is optimal for the high field (5-9T) of interest in contact with a non-superconducting layer. This optimal diffusion is preferably accomplished after a sufficient reduction such that the individual metal layers are 2.5 - 15 microns thick.

摘要： Des plaques perforées (10) dotées de très petits trous (14) de diamètre uniforme sur toute l'épaisseur de la plaque sont préparées par un procédé de tréfilage selon lequel une billette de métal réactif est placée dans une boîte d'extrusion du métal de plaque et ladite boîte est extrudée et réempilée de manière répétée, convertissant ainsi la billette en un fil du diamètre de trou désiré. A la taille finale, la tige est alors coupée en tranches et les fils sont éliminés par attaque sélective. Ce procédé est utile pour des métaux constitutifs de plaques intéressants pour des applications de régénérateurs à haute performance, en particulier le cuivre, le niobium, le molybdène, l'erbium et d'autres métaux des terres rares. Er3Ni, qui présente des propriétés thermophysiques favorables uniques pour de telles applications, peut être incorporé dans des régions des plaques en utilisant des boîtes d'extrusion (20) contenant de l'erbium et du nickel dans un arrangement empilé (53) avec les boîtes d'extrusion du métal de plaque, qui peut être du cuivre. Ledit arrangement est chauffé pour convertir l'erbium et le nickel en Er3Ni. Des plaques perforées ayant deux tailles de perforation (38, 42), dont l'une est suffisamment petite pour le stockage d'hélium sont également décrites.

摘要： Perforated plates (10) having very small holes (14) with a uniform diameter throughout the plate thickness are prepared by a 'wire drawing' process in which a billet of sacrificial metal is disposed in an extrusion can of the plate metal, and the can is extruded and restacked repeatedly, converting the billet to a wire of the desired hole diameter. At final size, the rod is then sliced into wafers, and the wires are removed by selective etching. This process is useful for plate metals of interest for high performance regenerator applications, in particular, copper, niobium, molybdenum, erbium, and other rare earth metals. Er3Ni, which has uniquely favorable thermophysical properties for such applications, may be incorporated in regions of the plates by providing extrusion cans (20) containing erbium and nickel metals in a stacked array (53) with extrusion cans of the plate metal, which may be copper. The array is heated to convert the erbium and nickel metals to Er3Ni. Perforated plates having two sizes of perforations (38, 42), one of which is small enough for storage of helium, are also disclosed.
