摘要：
The object of the work described was to develop a thermomechanical procedure for reducing the grain size of a cast high-purity tantalum ingot to ASTM 5 (62 U) or finer under conditions such that the diameter of the tantalum billet was no smaller at the end of the working sequence than at the start. The treatment found successful consisted of upsetting 52% at 500 F, extruding 52% at room temperature to original size, and annealing at 2000 to 2200 F.
