Microstructure and 3-d Effects in Fretting Fatigue of Ti Alloys and Ni-base Superalloys
Damage and plastic deformation accumulation in fretting fatigue occurs within a depth of a few crystallographic grains. Therefore, more accurate assumptions concerning length scale, damage volume, and the material model are needed to establish a more solid physical foundation necessary for next generation fretting fatigue damage prediction. Major thrusts include: (1) development and implementat...
متن کاملHigh Temperature Nanoindentation of Ni-base Superalloys
Novel techniques for characterizing and assessing the properties of Ni-base superalloys are becoming increasingly important to the accelerated development of new structural alloys and the advancement of physics-based mechanical property models. Instrumented indentation techniques have long served as a useful approach for probing the mechanical response of a wide range of engineering materials. ...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

متن کاملMicrostructural aspects of fatigue in Ni-base superalloys.
Nickel-base superalloys are primarily used as components in jet engines and land-based turbines. While compositionally complex, they are microstructurally simple, consisting of small (50-1000 nm diameter), ordered, coherent Ni(3)(Al,Ti)-type L1(2) or Ni(3)Nb-type DO(22) precipitates (called γ(') and γ(''), respectively) embedded in an FCC substitutional solid solution consisting primarily of Ni...
