ABSTRACT:
A method of forming a spinner for centrifuging fibers from molten material is disclosed. A dispersion strengthened metal is warm worked at a temperature above the minimum warm working temperature and below the recrystallization temperature of the metal to form a spinner having an annular peripheral wall and a plurality of ribs formed integrally with the peripheral wall and extending radially inwardly therefrom. The spinner is heat treated to recrystallize the metal to a coarse grain structure, and a plurality of fiber-forming orifices are formed in the peripheral wall.
