Molecular Dynamics Study on Tensile Strength of Nickel Based Single Crystal High-temperature Alloys Containing Voids
Nickel based metal high-temperature alloys have become key materials for high-temperature components of aviation and aerospace engines due to their excellent high-temperature mechanical properties.However,during the processing and forming process of this material,due to limitations in the level of technology,defects are inevitably generated,and voids are one of the defects.Voids have an undeniable impact on the overall mechanical properties of materials.Therefore,studying the specific role of voids on material properties is particularly important.In view of this,the focus is on analyzing the tensile deformation behavior of nickel based single crystal high-temperature alloys containing voids at different temperatures,strain rates,and crystal orientations,and explaining their deformation process by studying the microscopic mechanism of plastic deformation.
