Abstract

IN718 Plus superalloy is a wrought nickle based superalloy developed for improving mechanical propertirs and the service temperature of IN718 superalloy. The hot deformation of the alloy is one of the processing stpes of it. The addition of Boron and Zirconium can improve the creep properties of the alloy. The aim of this research, is to determine the hot working temperature range of IN718 Plus superalloy (based alloy) and to study the addition of the mentioned elements on the hot workability of it. The hot tensile test was performed on the based alloy in the temperature range of 950 to 1150oC and strain rate of 0.1 s-1. In addition, the test was performed on the alloys containing Boron and Zirconium at 950 and 1100oC. Results show that the best hot working temperature of the based alloy was achieved in the temperature range of 1000 to 1100oC due to the Dynamic recrystallization and its development. At 1150oC the decrease in ductility and inter-granular crack formation occurred by dissolution of precipitates and grain growth. The addition of Boron and Zirconium at 950oC increased the ductility compared to the based alloy which was due to Dynamic recrystallization. Therefore, addition of Boron and Zirconium results to decrease the temperature of maximum workability of it. At 1100oC, the ductility of the based and the alloy containing Zirconium was similar. Hence, it has been determined that the alloy containing Zirconium has a better effect on the increament of the workability window of the IN718 Plus superalloy.
