ABSTRACT:
A procedure for providing bores or other internal passages in hot isostatically pressed powder metal articles, especially those formed of nickel- or cobalt-base superalloys in which the passage is defined by a thin walled metal tube filled with refractory oxide (MgO or SiO.sub.2), which is embedded in the metal powder. After hot isostatic pressing the refractory oxide core is removed by leaching, leaving a smooth bore in the finished article.
