| 英文摘要 | This work described an experimental investigation on the recrystallization behaviors of the hot-rolled particle strengthened W (PSW) material. Upon annealing, the three processes, that is, recovery, recrystallization and grain growth, proceed in a discontinuous fashion for our PSW material, and two or more processes could simultaneously occur in local regions. At an annealing temperature spanning from 1300 degrees C to 1500 degrees C, recovery is in the dominant position which is verified by deformed grains over half of the whole, accompanying with a gentle decrease in hardness. Meanwhile, recrystallization nucleation, primary recrystallization and abnormal grain growth is identified at 1300 degrees C, 1400 degrees C and 1500 degrees C, respectively. Further increasing the annealing temperature to 1600 degrees C and 1700 degrees C, normal grain growth takes precedence over recovery, along with a marked reduction in hardness. TEM observations show that owing to microstructural heterogeneity induced by particle dispersion, local regions have an advantage in terms of strain energy storage over other regions during hot rolling, enabling a preferential recrystallization nucleation at 1300 degrees C; whereas nanosized TiC particles are capable of inhibiting grain growth at elevated temperature, and thus retard the recrystallization rate. In addition, our as-rolled PSW material exhibits a different texture, and the dominant alpha-fiber of {100}(011) and {112}(1-10) transforms into gamma-fiber texture of {111}(011) and {111}(-1-12) during recrystallization. |
