ABSTRACT:
A method of producing products from a mechanically alloyed, dispersion strengthened iron-base powder comprises consolidating the powder and working the consolidated body to the desired product shape. To obtain a desired grain size in the product, the process includes at least two stages of recrystallization annealing which may be effected after consolidation or alternatively at least one of the recrystallization anneals may be carried out while the material is still in powder form.
