摘要(Abstract)：

以GH4033合金锻坯为研究对象,在850~1200℃的温度范围内,借助激光共聚焦高温显微镜研究了加热温度和保温时间对GH4033合金锻坯晶粒尺寸变化的影响,推导并验证了具有普适意义的适合GH4033合金锻坯粗轧加热过程的晶粒长大模型。研究结果表明:随加热时间的延长,在850~1050℃加热时,晶粒尺寸变化不显著,且呈线性长大;1100~1200℃加热时,晶粒尺寸呈抛物线性长大,加热时间低于30 min时,晶粒尺寸随温度升高急剧长大,30 min后晶粒尺寸变化不显著,45 min后出现混晶现象。用于热加工的锻坯,加热温度低于1100℃时,有利于细化晶粒;加热温度高于1100℃时,保证坯料断面均温时间处于30~45 min可有效避免混晶。
