Abstract: A method for producing an alloy article, such as a valve or valve component, and an assembly for use therewith. The article is produced by hot isostatic compacting wherein a lining of prealloyed powdered metal of an alloy composition different than that of the remainder of the article is confined on a surface of an internal passage or cavity in the article. A solid lining element is provided contiguous with at least a portion of the powdered metal lining the surface of said internal passage, the lining element is of an alloy also different from that of the remainder of the article. The powdered metal and solid lining element are heated and then hot isostatically pressed to densify and bond the powdered metal and the lining element to the surface of the internal passage of the article to provide a clad lining of dissimilar metal.
