Effects of Pulse Current on Dynamic Recrystallization Behavior of GH4169 Superalloy

MATERIALS TRANSACTIONS, 2012
The pulse current was applied on the GH4169 alloy during tensile tests at 800°C. The effects of pulse current on the deformation behavior and recrystallization of the alloy were investigated, and the mechanisms were also discussed. The results show that the deformation resistance decreases and the elongation increases significantly by applying the ...
