EFFECTS OF ANNEALING TEMPERATURE ON INTENSITY AND DISTRIBUTION OF CRYSTAL TEXTURE IN Cu-12% Ag FILAMENTARY COMPOSITE
退火温度对双相纤维复合Cu-12%Ag合金织构的影响

Cu-12% Ag (mass fraction) strengthened by double-phase filamentary composite was prepared by heavy drawing. The effect of annealing temperature on the intensity and distribution of crystal texture in both Cu and Ag phases was investigated by annealing the composite at different temperatures. With the increase of annealing temperature up to 400 °C, the <111> component intensity decreases and the <100> component intensity increases in Cu phase while the <111> component intensity in Ag phase changes insignificantly. Annealing at temperatures higher than 400 °C enhances the texture intensities in both Cu and Ag phases. The texture formed by heavy drawing in Ag phase is more stable than that in Cu phase for the composite annealed at lower temperatures. The interface migrating, structure aggregating, fiber glomerating, and grain propagating from recover and recrystallization in annealing process generally change the intensities of the texture components formed by heavy drawing to form annealing texture. Therefore, the annealing texture components have the same orientation indexes as the deformation texture components.
