In this work, we investigate [110] symmetric tilt FCC grain boundaries (GBs) using a recently developed
approach for quasiperiodic interfaces with the phase field crystal model. GBs at arbitrary tilt angles can
be accurately obtained through our developed method. More significantly, at specific tilt angles associated
with the quadratic algebraic numbers √
2 and √
3 − 1, we find that quasiperiodic GBs exhibit generalized
Fibonacci sequences. The transition mechanism from quasiperiodic to periodic GBs is explored by examining
the displacement of spheres and spectral convergence. We also propose an accurate method to calculate the
GB energy at arbitrary tilt angles and analyze the factors affecting the energy. The results indicate that, except
for periodic GBs, the variation of GB energy with tilt angle is continuous
