Abstract

The aim of this study was to examine the effect of cobalt addition on the deformation and recrystallization behavior. The prepared material was Inconel 713C nickel base superalloy. In order to improve the deformability, the IN713C was modified by cobalt addition with 5 and 10wt%. Mechanical property was determined by room temperature tensile test with the strain rate of 10-3 s-1. The recrystallization was performed at 1473K for 300sec followed by oil quenching. The final microstructure becomes homogeneous through cobalt addition. Strength and work hardening rate were decreased during room temperature tensile test. By contrast, elongation was increased. Nucleation site was changed by cobalt addition. It was found that kinetics of recrystallization is dependent of the cobalt addition. The cobalt addition is attributed with ductility and recrystallization behavior and the latter is related to change of deformation behavior.
