Coarsening of particles involves a reduction of the total energy of the system. In fluids, the tendency for larger particles to grow at the expense of smaller ones is driven by the reduction of the total surface energy. In solids, the elastic strain energy Eel also needs to be considered. Reduction of Eel gives rise to particle alignment along elastically soft directions and changes of morphology as the particle volume increases. In addition according to several authors, reduction of Eel produces the splitting of particles that reach a critical size. Regular arrays of two, four and eight particles have been observed and explained in terms of splitting. However, splitting is unlikely from a micromechanical standpoint or as a consequence of the elastic interaction between particles. This investigation deals with the determination of translation order domains in coherent γ′ particles.

Quasi Static Process

An energy-based fatigue lifing method for the determination of the full-life and critical-life of in-service structures subjected to axial isothermal-mechanical fatigue (IMF) has been developed. The foundation of this procedure is the energy-based axial room-temperature lifing model, which states: the total strain energy dissipated during both a quasi-static process and a dynamic (fatigue) process is the same material property. The axial IMF lifing framework is composed of the following entities: (1) the development of an axial IMF testing capability; (2) the creation of a testing procedure capable of assessing the strain energy dissipated during both a quasi-static process and a dynamic process at elevated temperatures; and (3) the incorporation of the effect of thermal loading into the axial fatigue lifing model. Both an axial IMF capability and a detailed testing procedure were created. The axial IMF capability was employed to produce full-life and critical-life predictions as functions of temperature, which were shown to have an excellent correlation with experimental fatigue data. For the highest operating temperature, the axial IMF full-life prediction was compared to lifing predictions made by both the universal slopes and the uniform material law prediction and was found to be more accurate at an elevated temperature.
