Effect of annealing temperature on the texture of rolled tantalum and tantalum-10 wt % tungsten
The effect of annealing temperature on crystallographic texture was investigated on straight- and cross-rolled Ta and cross-rolled Ta-10wt %W sheets. Textures were measured on coupons cut from rolled sheets and annealed for one hour at 800 to 1550 C. In particular the effect of annealing temperature on volume fraction of grains having (II 1) and (100) crystal directions nearly aligned with the plate normal was investigated. In the pure tantalum sheets, increased annealing temperature lead to increased fractions of the (111) component. The same was true for the Ta-10wt %W but much higher temperatures were required to change the texture from a (100) type texture to a more (111) type texture. In addition, the influence of the annealing temperature on the sharpness of the texture; on the surface to centerline texture gradient; and on the in-plane symmetry of the texture was investigated.
