Study on Austenite Grain Growth Behavior for Q345E Steel
Author(s): 
Pages: 26-28
Year: Issue:  2
Journal: Heavy Casting and Forging

Keyword:  大型环锻件Q345E钢晶粒长大动力学模型;
Abstract: 以大型风电法兰常用材料Q345E钢为研究对象,应用金相显微镜分析研究了1 050~1 200℃区间内加热温度与保温时间对Q345E钢奥氏体晶粒长大的影响,并探讨了其动力学规律,获得了该钢奥氏体晶粒在高温下的长大规律,建立了晶粒长大的动力学模型,为Q345E钢大型锻件热加工工艺的制定提供了理论依据.
