Abstract
In order to control the primary recrystallization textures of pure molybdenum (pure Mo) and molybdenum-0.5mass% Ti-0.1%Zr-0.5%C alloy (TZM alloy) sheets, the effects of heating rates during annealing on the development of recrystallization texture were investigated by means of X-ray diffraction and line broadening techniques. Recrystallization at a rapid heating rate produces a texture which is substantially similar to the rolling texture in both pure Mo and TZM alloy sheets, i.e. a ({100} <011>+{111} <uvw>+{211} <011>) type texture. While recrystallzation at a slow heating rate produces a texture which is significantly different from the rolling texture in both sheets, i.e. a strong {111} <112> type texture. Changes in the primary recrystallization textures of both molybdenum sheets which were brought about at different heating rates are considered mainly to arise as a result of the difference in the orientation dependence of degree of recovery for the deformed fine structures (potential nuclei of recrystallization).
