Abstract
An article having a hollow cavity formed therein and a method for forming the same. The article includes a hollow structure having an open end and a body portion that is surrounded by a powdered material. The article is processed in, for example, a hot isostatic pressing operation, to permit a pressurized fluid to consolidate the powdered material. The pressurized fluid is permitted to pass through the open end of the hollow structure and into the body portion to thereby prevent the body portion from collapsing while the powdered material is being consolidated.
