Title:
POWDERED MATERIAL PREFORM AND PROCESS OF FORMING SAME
Document Type and Number:
WIPO Patent Application WO/2016/003563
Kind Code:
A3
Abstract:
A powdered material preform includes a pressed powdered metal or other powdered material, where the preform is processed and sealed so that a skin or shell is formed at the outer surface of the preform (such as via melting an outer layer or surface of the preform or via adding an outer layer around the preform or via a combination thereof), with an inner portion of the preform comprising pressed powdered material. The skinned preform may comprise a shape that is generally similar to that of a final product or part to be formed, or may simply comprise a puck or shape of approximately the same mass of the shape being formed, and the skinned preform is suitable for use in subsequent densification and/or consolidation processes or combinations thereof to form the final, fully processed part.
