Abstract
Verfahren zum Erzeugen eines Metallartikels mit einer endgultigen Dicke, das umfasst: Verformen eines Metallbarrens, um eine rechteckige Tafel mit einer Lange, Breite und Dicke zu bilden, wobei sich zwei der drei Dimensionen um nicht mehr als 25% voneinander unterscheiden, erstes Walzen der rechteckigen Tafel, um eine Zwischenplatte zu bilden, wobei das erste Walzen eine Vielzahl von Walzdurchgangen umfasst, und zweites Walzen der Zwischenplatte, um eine Metallplatte zu bilden, wobei das zweite Walzen eine Vielzahl von Walzdurchgangen umfasst und wobei jeder der Walzdurchgange des zweiten Walzens eine wahre Dehnungsreduktion von ungefahr 0,06 bis 0,18 pro Durchgang vorsieht.

High purity tantalum, products containing the same, and methods of making the same

TL;DR: In this paper, high purity tantalum metals and alloys containing the same properties are described and a process for making the high purity metal which includes the step of reacting a salt-containing tantalum with at least one compound capable of reducing this salt to tantalum powder and a second salt in a reaction container.

Correlating discrete orientation and grain size to the sputter deposition properties of tantalum

TL;DR: In this paper, the relationship between discrete crystallographic texture and grain size of tantalum with respect to the physical erosion behavior of planar tantalum sputtering targets was explored, and it was shown that both grain size and preferred orientation contribute to the deposition behavior.

Method for controlling the oxygen content in valve metal materials

TL;DR: In this paper, the acid leach solution is prepared and cooled to a temperature lower than room temperature prior to leaching the deoxidized valve metal material, such as tantalum, niobium, or alloys thereof.

Hollow cathode target and methods of making same

TL;DR: In this paper, the authors describe a method of cold-rolling a sputtering metal workpiece made of a valve metal to obtain a shape workpiece, which is then cold-rolled to obtain the sputtering target.

Refractory metal plates with uniform texture and methods of making the same

TL;DR: In this paper, a method of forming sputtering target from ingots of tantalum or niobium of requisite purity by the process of cutting the ingot to short lengths and pressure working (14, 22, 30, 34), along alternating essentially orthogonal work axes, is described.
