Study of a New Type High Strength Ni-Based Superalloy DZ468 with Good Hot Corrosion Resistance

Abstract:

Article Preview

The mechanical property, hot corrosion resistance and phase stability of a new-type directional solidification nickel-base superalloy named DZ468 that was developed independently by Institute of Metal Research, Chinese Academy of Sciences were investigated in this paper.The rupture properties of DZ468 alloy are nearly the same as those of DZ4125 alloy and its hot corrosion resistance property nearly the same as that of IN738 alloy under the same conditions. There is no finding TCP phase in the DZ468 alloy after aging at 900°C for 1000h. DZ468 alloy displays excellent phase stability.
