摘要
以蒸汽发生器用SA508-3钢大锻件为研究对象,通过JMatpro软件计算获得了热物性参数,利用Deform-3D软件模拟研究了热处理后锻件的组织和硬度,并采用小试样物理模拟方法进行了试验验证.结果表明,试验测试的组织和硬度与模拟结果吻合良好.可见,数值模拟技术是辅助确定大锻件热处理工艺合理性的有效工具,对缩短生产周期,降低成本,具有显著的实用价值.
Abstract
Taking SA508-3 steel forging for steam generator as research object,the thermophysical parameters for the steel were calculated by JMatpro software.After heat treatment,the microstructure and hardness of the forging were simulated by Deform-3D software.And the experimental verification was carried out by small specimen physical simulation method.The results show that the microstructure and hardness of both the experimental test and numerical simulation are in good agreement.It can be seen that numerical simulation technology is an effective tool to determine the rationality of heat treatment process for large forgings,which has significant value in shortening production cycle and reducing cost.
