Microstructure and High-Temperature Creep Behavior of NiAl-25 at.% Cr Intermetallic Compound

Abstract:

The creep behavior and mechanisms of extruded NiAl-25Cr alloy at elevated temperatures have been studied in the paper. Analysis of the creep data over the temperature range 1073-1123 K reveals two distinct regions of creep behavior present in this material. At lower temperature, the creep characteristics are consistent with mobility-controlled deformation where viscous glide of dislocations controls creep. At higher temperature, the creep characteristics are consistent with a structure controlled creep process where some form of dislocation climb controls creep deformation.
