1. A process for producing an article of manufacture for glass making from a mechanically alloyed or oxide dispersion strengthened alloy including the steps of:
- warm working the alloy at temperatures below its recrystallization temperature;
annealing the warm worked article to recrystallize the alloy to a coarse grain structure; and
hot forming the article of manufacture for glass making.

Abstract
A process for producing an article of glass manufacture is disclosed in which oxide dispersion strengthened alloys are used to produce complicated shapes. The process includes a critical thermomechanical processing sequence to recrystallize the alloy into a coarse grain structure for high temperature service.

2. A process for producing an article of manufacture for glass making from a mechanically alloyed or oxide dispersion strengthened alloy including the steps of:
-
warm working the alloy at temperatures below which substantial recrystallization occurs; hot forming the article of manufacture for glass making; and annealing the hot formed article to effect recrystallization of the alloy to a coarse grain structure.

4. A process for producing spinners for forming glass fibers from a mechanically alloyed or oxide dispersion strengthened alloy including the steps of:
-
warm working the bar stock of the alloy at temperatures below which substantial recrystallization occurs to form a plate; annealing the warm worked plate above this temperature to effect recrystallization to a coarse grain structure; and hot spinning the annealed plate to the shape of a spinner. - View Dependent Claims (5, 7, 8, 9, 10, 11, 12, 13)
