Methods for producing forged products and other worked products are disclosed. In one embodiment, a method comprises using additive manufacturing to produce a metal shaped-preform and, after the using step, forging the metal shaped-preform into a final forged product. The final forged product may optionally be annealed.

Methods for producing forged products and other worked products

A tantalum sputtering target characterized in that on the surface of tantalum target, the area ratio of crystal with any of orientations (100), (111) and (110) providing that the sum of all crystal orientations is 1 does not exceed 0.5. Thus, there can be obtained a target for tantalum sputtering excelling in film formation characteristics such that the film formation speed is high, the uniformity of the film being excellent, with the occurrence of arcing and pulverization reduced.

Tantalum sputtering target

Largely alleviating the orientation dependence by sequentially changing strain paths

A method of making metal articles as well as sputtering targets is described, which involves deforming an ingot to preferred dimensions In addition, products made by the process of the present invention are further described

Methods of producing deformed metal articles

Methods and apparatus for rolling metal sheet or plate are provided. The method comprises the step of feeding the metal plate or sheet into a rolling mill at an angle. The apparatus comprises a rolling mill having a tilted feed table, or an apron upon which a transfer table and tilted feed table can rest. Through-thickness gradient and shear texture can be improved using the methods and apparatus of the invention.

Methods and apparatus for controlling texture of plates and sheets by tilt rolling

A process is described for processing metal which includes clock rolling a metal plate until the desired thickness is achieved to form a rolled plate. Sputtering targets and other metal articles are further described.
