摘　　要：为了研究新型合金在高温状态下的晶粒长大行为,进行了Haynes 282合金在973~1 373 K条件下保温0~10 800 s的晶粒长大实验,通过实验分析了保温时间和保温温度对其晶粒尺寸的影响,研究了晶粒尺寸在其实验条件下的演变规律。由此构建了符合Haynes 282合金晶粒长大的数学模型,该模型的建立能够有效表征Haynes 282合金在高温下的晶粒长大行为。In order to study the grain growth behavior of a new-type nickel-base superalloy at elevated temperature,grain growth tests are carried out of Haynes 282 alloy within the holding temperature range from 973 to1 373 K and holding time range from 0 to 10 800 s. The influence of the insulation time and insulation temperature on the grain size is analyzed,and the evolution law of the grain size under the experimental conditions is studied. The mathematical model of grain growth of Haynes 282 alloy is constructed,which can effectively characterize the grain growth behavior of Haynes 282 alloy at high temperature.
