| Research Abstract |
It has been concluded that the phase-field-crystal simulation can express the dependencies of temperature, strain rate and grain size on the deformation of polycrystalline metal. To achieve the high speed computing of phase-field-crystal simulation, GPGPU has been employed for the conventional phase-field simulation. As a result, it has been confirmed that GPU phase-field simulations achieve about 70 times performance speedup for CPU. Furthermore, by performing the static recrystallization simulations using multi-phase-field method, it has been shown that the misorientation dependencies of grain boundary energy and mobility are important to form the recrystallization texture.
