摘要:

晶粒细化是控制金属材料组织的最重要、最基本的方法。本文利用Deform软件对船用大型长轴类锻件的锻造过程进行数值模拟,改变锻打方法,分析晶粒细化的变化趋势。模拟结果表明:随着接砧量的增加,晶粒尺寸变小;随着压下率的增大,晶粒尺寸先减小后增大,当压下率为12.5%时,晶粒尺寸趋于最小。因此,通过改进锻打工艺可以有效促进大型锻件的晶粒细化,提高锻件质量。

Grain refinement is the most important and the most basic method to control the structure of metal materials.Using software Deform, the forging process of large marine shaft forgings was simulated, and through changing forging method, the change trend of grain refinement was analyzed.The results show that with the increase of overlapping length,the grain size decreases; with the increase of forging percentage,the grain size decreases first and then increases, when forging percentage is 12.5%, the grain size is almost the smallest. So the grain refinement can be promoted effectively and the forging quality can be improved by improving forging technology for large forgings.
