Query: Cyclic-loading microstructure-property relations from a mesoscale
  perspective: An example of single crystal Nickel-based superalloys   Past models of stress-strain response under cyclic loading mainly rely on
macroscopic equations which consider microstructure evolution indirectly or
simply discard microstructure information. Modern materials science, on the
other hand, seeks quantitive descriptions for the relations between
microstrucutre and loading response. In the present work, we show a promising
mesoscale phase-field framework which can describe co-evolution of phase/grain
and defect microstructures, reveal microstructure mechanisms and simultaneously
predict deformation properties as a natural outcome of microstrucuture
interactions. The energy functionals for phase/grain and defect microstructures
are constructed, followed by functional variation which leads to governing
equations. Applying the developed framework to high temperature cyclic loading
of single crystal Nickel-based superalloys, the simulated results show that
cyclic loading-microstructure-property relations can be principally revealed.
In the short term perspective (in one cycle), dislocations move back and forth,
leading to cyclic loops consistent with characteristics observed in
experiments. The plastic strains are one order of magnitude smaller than total
strains, which explains why the cyclic loops are very "thin". In the long term
perspective, all $\gamma\gamma'$ microstructures exhibit directional coarsening
similar to creep under zero cyclic loading ratio, with the extent of rafting
slight dependent on cyclic waveform, period, etc. The plastic strains are
sensitive to cyclic loading conditions both in terms of curve shape and in
terms of magnitude.
