摘要
应用CAFE法,模拟了易切削钢9SMn28三维微观凝固组织及其结晶过程。模拟结果与实验结果吻合较好,模拟结晶过程与实际结晶过程相符。模拟优化了易切削钢9SMn28最佳的锰硫比,确定的最佳值为4.44,即锰为1.2wt%、硫为0.27wt%,并通过热力学计算分析了原因。
The 3D-solidification microstructure and crystallization of 9SMn28 free-cutting steel weresimulated in solidification process based on CAFE methods, and the simulation results were consistent with that of experiments. The optimization of rate of manganese to sulfur was simulated for free-cutting steel 9SMn28, and the result was 4.44, thus manganese content was 1.2wt% and sulfitr content was 0.27wt%, the simulation results were analyzed by use of thermodynamics.
