Y2O3 is a favourable reinforcement for the oxide dispersion strengthened superalloy due to its good high temperature stability, excellent strength and large elastic modulus. In this work, Y2O3 is introduced into the K4169 superalloy aiming to improve its high temperature properties. The high quality Y2O3 and K4169 powder mixture can be obtained with the addition of the process control agent of stearic acid after high energy ball milling, and the Y2O3/K4I69 composite with uniformly dispersed reinforcement of nanoscale Y2O3 particles are finally synthesized with the ball-milled powders by using spark plasma sintering.
