摘要

摘要: 建立了基于析出、回復和再結晶之間交互作用的低碳含鈮鋼組織預測模型,用于模擬低碳含鈮鋼熱軋道次間隔期間粗晶奧氏體的再結晶及析出行為,并討論了模型在繪制低碳含鈮鋼的再結晶-析出-時間-溫度(RPTT)圖中的應用.結果表明,模型對兩種低碳含鈮鋼在熱變形道次間隔期間內粗晶奧氏體的組織演變過程的模擬結果與測試數據符合較好,可以有效預測不同低碳含鈮鋼在不同工藝條件下的析出和再結晶行為.

Abstract: A microstructural prediction model of low carbon Nb-containing steels based on the interaction of precipitation, recovery and recrystallization was developed to simulate the evolution of precipitation and recrystallization of coarse-grained austenite in low carbon Nb-containing steels during pass interval of hot deformation. The application of this model in making the recrystallization-precipitation-temperature-time diagram (RPTT) of low carbon Nb-containing steels was discussed. The simulation results are well coincident with the experimental data of two low-carbon Nb-containing steels, indicating that the behaviors of precipitation and recrystallization can be predicted using this model for different low carbon Nb-containing steels at various processing conditions.
