The Sintered Nickel-Base Superalloy. IV. Morphology Change of gamma ' Precipitates During Recrystallization and Creep

Morphology change of gamma ' precipitates in nickel-base superalloy IN-100 prepared by liquid phase sintering and swaging was investigated during recrystallization and creep (1323K, 66.6 MPa). The results obtained were as follows: (1) In the swaged specimens, large-sized and cellular gamma ...

Zusammenfassung:Morphology change of gamma ' precipitates in nickel-base superalloy IN-100 prepared by liquid phase sintering and swaging was investigated during recrystallization and creep (1323K, 66.6 MPa). The results obtained were as follows: (1) In the swaged specimens, large-sized and cellular gamma ' precipitates appeared behind the migrating boundary of recrystallized grains in a similar manner as that in discontinuous precipitation. On the other hand, uniform and fine gamma ' precipitates appeared in the strain-free specimens subjected to solution treatment after swaging. 15 ref.--AA
