Effect of Nb on Microstructure and Mechanical Property of Novel Powder Metallurgy Superalloys During Long-Term Thermal Exposure

Microstructure and mechanical properties of novel Ni-20Co-12Cr superalloys, with and without Nb addition, were systematically studied during long-term thermal exposure. With increased exposure time, the average diameter of the γ’ precipitates increased in both alloys in succession; this is more obvi...
