摘要: A clad article of a substrate of one powdered metal that is clad with a second dissimilar powdered metal. A separation layer may be provided between the substrate and the clad layer to separate these layers during consolidation and to facilitate bonding thereof. The consolidation operation may be performed by hot isostatic pressing of the powders within a deformable container.

摘要: A method for producing an autogenous welded tubular metal article having a substantially uniform grain size, including the weld-affected area thereof. This is achieved by applying to the metal article a series of cold reduction and annealing operations that in combination render the grain size of the weld-affected area uniform with respect to the remainder of the cross-section of the article, and particular the visual appearance of the cross-section.
