Thermomechanical Processing and Continuous Cooling Transformation Behavior of IN-718

Abstract

The influence of homogenization treatment and cooling rates on the transformation characteristics of IN-718 alloy were studied. In addition, the effect of thermomechanical processing on the recrystallization behavior of this alloy was also investigated. The results of this investigation led to both the construction of continuous cooling transformation diagrams and to the establishment of a temperature-deformation-recrystallization map for this alloy.
