Original Abstract

Polycrystalline nickel-base superalloy MAR-M-247 is used for high temperature applications requiring excellent combination of fatigue properties, creep resistance and surface stability. In the present work, the high temperature low cycle fatigue behaviour of cast nickel-base superalloy MAR-M-247 in as received condition and in hot isostatically pressed (HIP) condition was studied. The microstructure of the materials is characterized by dendritic grains, carbides and casting defects. Distribution and size of defects in both materials were studied. Beneficial effects of HIP process on cyclic stress-strain and fatigue life curves are discussed.

Keywords

MAR-M247, High Temperature, Low Cycle Fatigue.
