| 中文摘要 | The microstructural evolution of submicron sized ferrite in bimodal structural ultrafine grained ferrite/cementite steels with 0.15 pct carbon content and 0.45 pct carbon content upon annealing below the austenized temperature was investigated. The average grain sizes of the ferrites with a normal density and with a high density of cementite particles were plotted, respectively, as a function of the annealed temperature and time, and exhibited different coarsening behaviors. The average grain sizes of the ferrites with a normal density of cementite particles gradually coarsened by increasing the annealing temperature or time, while those with a high density of cementite particles hardly changed at first, and then coarsened after reaching a certain annealing condition. The coarsening of the ferrite grain size in the steel with 0.15 pet carbon content occurred much more readily than that in the steel with 0.45 pet carbon content upon annealing. The spacing and the critical spacing of cementite particle were measured and hypothetically calculated, respectively. The size and the distribution of cementite particles was one of the critical factors affecting the microstructural evolution in this type of cementite particle spherodized steels. Most of the coarsening of the ferrite grain size occurred after the cementite particle spacing reached the required critical value. |
