ABSTRACT:
A metal electroform suitable for hot isostatic pressing (HIP) of metal powders and the fabrication process therefor is disclosed. Ordinary nickel electroplate is permeable to gases during HIP, e.g., at 1200.degree. C. and 100 MPa. An exemplary improved container is comprised of a first electroplated layer of nickel, a second layer of copper and a third layer of nickel, wherein the container has been heated to about 1150.degree. C. and then cooled, to cause fusing of the second lower melting point layer. During fusing there is limited alloying between the layers, the first and third layers retaining the desired container shape.
