Notes:
Texture and microstructure of gold sheet were investigated during deformation andsubsequent annealing. The Brass, S and Copper (β-fiber) orientations are closely connected togetherin the deformed microstructure. Recrystallization texture also was examined during isothermalannealing at 500°C with reduction in area. Initial rolling textures with rotated cube and β-fiberresulted in the cube and recrystallized β-fiber orientations after annealing. A two dimensional MonteCarlo (MC) method was used to simulate primary recrystallization in gold sheet. A function ofboundary misorientation was introduced to consider anisotropic properties of grain boundary energyand mobility. Stored energy associated with orientations in the deformed grains was evaluated byreconstructing of data measured using electron back-scattered diffraction (EBSD). The nucleation atan initial stage of recrystallization was found at the high angle grain boundaries (HAGBs) and graininteriors. The main texture components obtained by the simulation were similar to those obtainedexperimentally except cube component
