采用分子动力学(Molecular Dynamics
MD)模拟的方法,针对FeCrAl合金的高温蠕变性能及本构关系开展研究,分析了温度、应力和晶粒尺寸等参数对稳态蠕变速率的影响规律,拟合得到蠕变本构关键参数,包括蠕变激活能Qc、应力因子n和晶粒因子p。结果表明,相比于晶粒尺寸和合金成分,温度与应力对蠕变本构参数的影响更大。随着应力的升高,n的变化尤为显著。低应力下n为1.2~1.5,中高应力下n由2.0增至4.0以上。当温度低于1000 K,应力变化对Qc影响不显著,不同应力下Qc为0.1~0.2 eV。但在高温条件下,Qc随应力升高由0.5 eV增至1.0 eV。当晶粒尺寸d小于12 nm
p随温度和应力的升高由1.5增至3.5左右,当d达到12 nm以上时,p为0.7~1.0。
