摘要

The sheet rolled" from the [0111(100) oriented tungsten single crystal billet had an Increasingly superior recrystallization temperature over the [100] (001), [100] (011). and [0111(011) orientations at all reductions in thickness tested in the order given. This substantiates the premise on which the study was begun that the recrystallization temperature is dependent on the initial billet rolling plane-rolling direction orientations. This dependence seems related to the slip systems available for deformation and the values of shear stress from the compressive rolling stress resolved on these slip planes. A special "easy deformation mode" is shown as possibly existing in those rolling orientations having the highest recrystallization temperatures in which a slip direction and rolling direction ace coplanar with a force direction acting on a favorably oriented slip plane to give a .high resolved shear stress and. cause deformation to occur in the. direction of rolling. In addition, the varying rates of strain hardening, tensile strengths, recrystallization initiation, and recrystalllsed grain size are displayed as a function of billet orientation. A single crystal billet scale-up, as-rolled and rolled-recrystallized sheet texture study, and alloy program are recommended.
