dc.description.abstract Introduction: This study investigated the mechanical properties of platinum-graphene nanocomposites synthesized through powder metallurgy, focusing on how temperature and pressure affected their behavior. The aim was to understand these influences, which are crucial for industrial and medical applications. Using molecular dynamics simulations, the study investigated to optimize these materials for enhanced performance, particularly in improving the biocompatibility of platinum-based materials for medical use. Development: This study aimed to analyze the impact of various temperatures and pressures on the stress-strain curve, ultimate strength, and Young's modulus of platinum-graphene nanocomposites using molecular dynamics simulations. The study examined how these factors influenced the material's performance under different conditions. Conclusion: The results indicate that ultimate strength decreased from 116 to 105 MPa, and Young's modulus decreased from 1099 to 1000 MPa as temperature increased from 300 to 400 K. This decrease was due to higher temperatures causing increased atomic vibrations and weaker interatomic bonds, reducing resistance to deformation and failure. Similarly, fracture stress decreased from 106.744 to 97.655 MPa, and the strain ratio decreased from 27.15 to 25.92 at the fracture stress point with rising temperature. Conversely, changing the pressure from 1 to 5 bar resulted in an increase in Young's modulus and ultimate strength to 1297 MPa and 137 MPa, respectively. Higher pressure enhanced atomic packing, strengthening interatomic bonds and improving fracture resistance. At 5 bar pressure, fracture stress rose from 106.744 to 119.40 MPa, while the strain ratio at the fracture stress point increased from 27.15 to 31.914. In conclusion, temperature and pressure significantly influenced the mechanical properties of platinum-graphene nanocomposites, impacting their industrial and medical applications. en_US
