摘要
通过热力学计算和析出物形貌观察表明,析出物对铸坯晶粒的生长起到一定的限制作用。6道次连轧模拟计算结果与观察结果吻合较好,同时也表明,再结晶是组织细化的主要原因。各种强化方式定量计算的结果表明,细晶强化是主要的强化方式,沉淀强化和位错强化次之,且它们对屈服强度的贡献相近。
By thermodynamics analysis and precipitates observation, it is concluded that the grain growth in continuous cast thin slab is restrained due to precipitation The simulation results are reasonably in good agreement with experimental observation, which also showed that recrystallization is the main reason for microstructure refinement Refinement strengthening is the primary strengthening mode Precipitation strengthening and dislocation strengthening are second to it, their contributions to yield strength are almost equal
