FABRICATION AND DEFORMATION OF TUNGSTEN SINGLE CRYSTALS. PART 1. EFFECT OF BILLET ROLLING PLANE AND ROLLING DIRECTION ON THE RECRYSTALLIZATION TEMPERATURE OF SHEET FROM TUNGSTEN SINGLE CRYSTALS. PART 2 RECRYSTALLIZATION OF WORKED SINGLE CRYSTALS OF TUNGSTEN.
Abstract
The sheet rolled from the 011(100) oriented tungsten single crystal billet had an increasingly superior recrystallization temperature over the 100(001), 100(011), and 011(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 are 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.
