ABSTRACT:
A method is provided for forming articles from difficult to fabricate materials with precise internal dimensions. The article is first formed to approximate dimensions as a body using the material in powdered form. Plasma spray forming is proposed. The powder formed body is then brought to its final dimensions by consolidating and densifying the body about a densifying mandrel having a coefficient of expansion which is higher and outer dimensions which are slightly smaller than that of the body.
