摘要： A process for forming a metallic sputter target and a metallic sputter target product are provided. The process provides a dense homogenious bulk material of high strength comprising ductile metal components which forms a brittle composition when alloying. The process employs a mixture of individual components at least one of which being ductile at room temperatures. The individual components can be all metals, or a mixture of metals and non-metals. The individual components are formed into a powder mixture in a first step. Unlike hot pressing or other melting techniques which can cause ductile components to alloy into brittle materials, the powder mixture is cold pressed to form a shaped body which is thereafter densified by repeated working at temperatures below the lowest of the melting points of the individual components. This treatment occurs under conditions of material flow and cold welding. The resultant product is a dense target wherein the individual components continue to exist as a mixture of powders. The sputter target of the invention has the density and mechanical strength required of commercial sputter targets. The target product is machinable.

摘要翻译： 提供了形成金属溅射靶和金属溅射靶产物的方法。 该方法提供了高强度的致密均匀散装材料，其包括当合金化时形成脆性组合物的延性金属组分。 该方法采用单个组分的混合物，其中至少一种在室温下是延展性的。 单个组分可以是金属或金属和非金属的混合物。 在第一步中将各个组分形成粉末混合物。 不同于可将韧性组分合金化成脆性材料的热压或其它熔融技术，粉末混合物被冷压以形成成型体，然后通过在低于各组分熔点最低点的温度下重复加工而致密化。 这种处理发生在材料流动和冷焊条件下。 所得产物是致密靶，其中各组分作为粉末的混合物继续存在。 本发明的溅射靶具有商业溅射靶所需的密度和机械强度。 目标产品是可加工的。

摘要： The invention relates to a process for producing a riveted joint using a riveting tool. The essential feature is that a pin-shaped blank of a recrystallized, coarse-grained iron-based or nickel-based ODS superalloy having a grain elongation in the longitudinal direction of 5:1 to 50:1 is used for the rivets. The production of the rivet heads is performed under defined process temperatures, at a pin temperature between 600.degree. and 1000.degree. C. and at a tool temperature between 50.degree. and 300.degree. C.
