GRAIN REFINEMENT OF URANIUM BILLETS

Patent ·
OSTI ID:4081480

A method of refining the grain structure of massive uranium billets without resort to forging is described. The method consists in the steps of beta- quenching the billets, annealing the quenched billets in the upper alpha temperature range, and extrusion upset of the billets to an extent sufficient to increase the cross sectional area by at least 5 per cent.
