Study on the Influence of Temperature and Strain Rate on the Tensile Behavior of Ti-5Mo-5Cu alloy Biomaterial Alloy:A Molecular Dynamics Simulation

Abstract

Abstract The development of efficient biomedical bone tissue implants has invoked significant impact in the biomedical research fields and aids the aged populated peoples. In this examination, the mechanical features of implant material (Ti–5Mo–5Cu alloy) has been investigated using the molecular dynamics method under varying temperature and strain rate to understand its physical phenomenon and through this study, it is found that the strain rate has offered a complex beneficial impact over the material characteristics such as yield stress and yield strain, owing to its higher impact over the restraining behavior between various atoms and strain toughening effect related to the temperature effect. Furthermore, the shear strain and point defect analysis has confirmed that the structural alteration and the establishment of multiple dislocations lead to induce the deformation behavior of Ti–5Mo–5Cu biomaterial alloy. Additionally, the radial distribution analysis has stated that the introduction of higher ambient temperature leads to invoking multiple dislocations which are responsible for the deformation behavior and cause the major reduction in tensile properties.
