Computer-implemented processes for making refractory metal pots, including: cutting an a refractory metal ingot into a first workpiece; subjecting the first workpiece to multiple upset forgings, annealings in a vacuum or inert gas to a temperature sufficiently high to cause at least partial recrystallization, forging-backs, and rollings to form a plate; wherein the forged, annealed workpiece undergoes a reduction in thickness after at least one rolling pass and is turned between at least one pass, to form the plate; and deep drawing the plate to form a pot; wherein dimensions of at least one workpiece or plate suitable for processing into a pot are pre-determined with a computer-implemented finite element modeling assessment method. |
