Creep behavior and characterization analysis of Mg-1.8Zn-0.3Ca alloy:a molecular dynamics analysis

Abstract The addition of Zinc (Zn) and Calcium (Ca) on the Magnesium (Mg) has invoked better biocompatibility in various orthopedic applications. But this addition (Zn and Ca) leads to inducing greater modifications in the creep characteristics. In this current study, a study on the creep characterization of Mg-1.8Zn-0.3Ca alloy has been examined using molecular dynamics analysis. The creep analysis has been focused on numerous grain sizes and creep environments such as temperature and pressure to analyze its effect on the creep performance and its features. Further, the creep performance, radial distribution function, dislocation length, and structural and microstructural transformation under various grain size and deformation time has been confirmed by the modifications in the deformation mechanism and its features under various grain size and creep conditions.
