Abstract Scope |
This study examines the influence of precipitates on the creep strain rate of the Al0.3CoCrFeNi multi-principal element alloy (MPEA), recognized for its superior creep resistance. Utilizing the Multiphysics Object Oriented Simulation Environment (MOOSE), an open-source finite element solver, we have developed a robust framework to analyze these interactions using the crystal plasticity finite element method. Comprehensive creep tests were conducted to assess the alloy's behavior under prolonged stress at elevated temperatures, providing critical insights into its deformation mechanisms. Furthermore, our research investigates the dislocation climb properties within this MPEA. The effects of two types of precipitates are explored. The outcomes of this study aim to enhance the understanding of the mechanical behavior of Al0.3CoCrFeNi MPEA and contribute to the advancement of materials with exceptional high-temperature performance. |
