Impact of point defects on the creep behavior of MgY Polycrystal:A molecular dynamics study

The points defects offer greater fluctuations in the material features of many materials. In this study, the impact of point defects on the compressive creep performance of monolithic MgY bimetallic polycrystal compound has been examined under various creep circumstances through a molecular dynamics method and found that the creep circumstance has invoked greater impact on the MgY related to the point defects, owed to the existence of greater diffusion and grain rotational behavior. The existence of point defects offers a lowermost impact on the creep performance and its feature, owing to the existence of moderate resistance against its deformation as a result of creep deformation time and the trend is irrespective of the applied pressure and temperature.
