摘要： A process for making a composite tube uniquely suited for use in ethylene pyrolysis furnaces wherein the tube comprises an outer shell (32) made from a wrought or cast Fe-Ni-Cr heat resistant alloy and an inner core made from INCOLOY alloy MA956 powder. The outer shell (32) and powder core (34) are heated and simultaneously extruded to form a composite tube. The process is carried out at a temperature of preferably less than 1200°C and for a time so as to prevent recrystalization of the very fine grain structure in the alloy MA956. This un-recrystalized fine grain structure permits pilgering and/or cold drawing of the extruded composite tube to final size. The composite tube provided by the present invention is uniquely suited for use in the petrochemical and chemical process industries, so as to increase the efficiency and productivity of their respective processes. The thin core layer (34) of alloy MA956 provides high resistance to carburization and coke formation heretofore caused by the hydrocarbon feedstock flowing through the composite tube, while the outer shell (32) of Fe-Ni-Cr heat resistant alloy provides overall strength and rigidity to the tube. The use of the outer shell in the composite tube also solves the joining problem heretofore encountered in joining alloy MA956. A root pass or passes using an alloy MA956 filler metal followed by overlay welding passes using a filler metal compatible with the heat resistant alloy, such as INCONEL alloy 617 or FM 25/35, joins the outer shells of adjoining composite tubes and, thus, solves the welding problem.
摘要翻译：一种制造独特地适用于乙烯热解炉的复合管的方法，其中管包括由锻造或铸造的Fe-Ni-Cr耐热合金制成的外壳（32）和由INCOLOY合金MA956粉末制成的内芯。将外壳（32）和粉末芯（34）加热并同时挤出以形成复合管。该工艺在优选低于1200℃的温度下进行一段时间，以防止合金MA956中的极细晶粒结构的再结晶。这种未重结晶的细晶粒结构允许挤压复合管的拉拔和/或拉伸成最终尺寸。本发明提供的复合管独特地适用于石化和化学工业，以提高其各自工艺的效率和生产率。合金MA956的薄芯层（34）对流过复合管的烃原料造成的渗碳和焦炭形成提供了高的抵抗力，而Fe-Ni-Cr耐热合金的外壳（32）提供了整体强度，管的刚度。在复合管中使用外壳也解决了在接合合金MA956中遇到的连接问题。使用合金MA956填充金属根管道或通过，然后使用与耐热合金（例如INCONEL合金617或FM 25/35）相容的填充金属进行覆盖焊接，连接相邻复合管的外壳，解决焊接问题。

摘要： The invention relates to a method for producing hollow nickel titanium profiles with a small external diameter and/or small wall thickness by means of deformation, especially extrusion. According to the inventive method, a composite block is formed, comprising a solid core and one or several hollow blocks surrounding said core. The core and the hollow blocks are made of nickel titanium. The parts of the composite block are separated after deformation to obtain a wire (3a), a tube (1a) with a small diameter and a tube (5a) with a larger diameter.

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： 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： The present disclosure provides a method of manufacturing a composite material. The method can include compacting a copper alloy powder into a plurality of substantially uniform compressed sub-assemblies such that the copper alloy powder has a density that is greater than 50%. The plurality of compressed sub-assemblies can be layered relative one another within an aperture of a shell, the plurality of compressed sub-assemblies to form a consecutive assembly of compacted copper alloy. The shell may include one of the following: a precipitation hardened copper alloy, copper alloy, and carbon steel. The consecutive assembly can be sealed within the shell to form a billet. The billet can be hot-extruded to form a rod, and the extruded rod can be further drawn to form a composite wire of a desired diameter.
