690合金高温连续变形动态再结晶行为
Dynamic recrystallization behavior of Inconel 690 during hot contin-uous deformation
摘要
Abstract
Continuous hot deformation testing of Inconel 690 cone samples at three different temperatures (1100, 1140 and 1180 ℃) was performed with a hydraulic press machine. Dynamic recrystallization in the alloy during con-tinuous hot deformation was studied by optical microscopy and back scattering diffraction. It is found that dynamic recrystallization in Inconel 690 happens during continuous hot compression deformation. The nucleation of dynamic recrystallization is in the order of triple junctions of grains→strain-induced boundary migration→twin boundaries→inside of grains, and the twin promotes the recrystallization process of Inconel 690.关键词
