英文摘要
The new material processing based on the control of grain boundary microstructure for improvement of fatigue property was discussed for SUS304 stainless steel and 6010 aluminum alloy with a face centered cubic (FCC) structure. A clue to control of grain boundary microstructure for these FCC materials with different stacking fault energies was obtained. It was revealed that the fatigue fracture was controlled by introducing higher fraction of coincidence site lattice boundaries with low grain boundary energies.
