Abstract
A nickel-based alloy useful in the manufacture of a glass fibre centrifuge of which the composition consists essentially of the following elements expressed as percentage by weight: ______________________________________ Cr 27.5-29.5% W 6.5-7.8% C 0.69-0.73% Fe 7-10% ______________________________________ the remainder substantially being nickel and having in its crystalline structure M.sub.23 C.sub.6 type carbides, M being chromium, at least one equivalent metal, or combination thereof, the M.sub.23 C.sub.6 carbides being substantially secondary.
Claims8
A glass fibre centrifuge as cast from a nickel-based alloy consisting essentially of the following elements expressed in percentage by weight:
- ______________________________________ Cr 27.5-29.5% W 6.5-7.8% C 0.69-0.73% Fe 7-10% ______________________________________
- the remainder substantially being nickel and having in its crystalline structure fine M.sub.24 C.sub.6 carbides distributed homogeneously in the alloy matrix, M being chromium, at least one equivalent metal, or combinations thereof, the M.sub.23 C.sub.6 carbides being substantially secondary carbides formed from the cast alloy comprising M.sub.7 C.sub.3 primary carbides.
