Beschreibung
Zusammenfassung:	Structural components of at least one intermetallc compound and having complicated contours, are made by the steps of preparing a powder mixture of elemental metal powders including at least one powder of a low melting metal element or component and one powder of a high melting metal element or component that subsequently are to form the intermetallic compound. The powder mixture is then sintered to form a sintered body which is machined to a contour close to the finished contour and to dimensions close to the final dimensions. The so machined and shaped part is enveloped with an envelope of the high melting metal element or component. The enveloped part is subjected to a hot isostatic reaction pressing whereby the intermetallic compound is formed.
