This study analyzes the creep mechanisms of titanium alloys at room temperature through molecular dynamics simulations, focusing on the influence of grain-boundary interactions and grain misorientation angles on creep behaviors. The molecular dynamics results show that grain-boundary sliding and dislocation gliding within the crystal structure are the two key factors contributing to creep failure. Grains with larger misorientation angles exhibit more stable boundaries and greater resistance to creep, whereas smaller misorientation angles promote boundary slip and result in enhanced creep deformation.
