Abstract
The process of the invention relates to forming MA iron-base ODS alloys. A billet of iron-base ODS alloy is provided. The billet is consolidated at a temperature within a predetermined range of sufficient temperature for formation of coarse and/or fine grain sizes during a final heat treatment. The consolidated billet is worked into final form. The object is annealed to recrystallize grains to a size determined by the temperature of the consolidation and the working of the extruded billet.
