摘要
Abstract
The static recrystallization behavior and kinetics of Haynes230 superalloy were investigated. The results show that homogeneous and fine grains of the alloy are obtained through annealing at 1100 ～ 1150℃ after cold rolling. The relationship between volume fraction of the recrystailization grains and annealing time can be described by the JMAK equation. Based on the experimental data, the calculated activation energy decreases range from 402kJ/mol to 318kJ/mol with the cold deformation increasing. As the temperature rose, the time for recrystallization completion shortened with range of 74.51 ～ 5.43min. The temperature had significant influence on the velocity of recrystallization. At the meantime, the recrystallization kinetics curve of Haynes230 superalloy was worked out, which is a theoretical guidance for the microstructural refinement.关键词
