Abstract Scope |
Materials modelling plays an increasingly important role in accelerating the development of novel metal matrix composites for various applications in extreme environments. Predicting the influence of processing parameters and material chemistry on the composite properties using ICME (Integrated Computational Materials Engineering) tools allows for composite design that achieve better trade-off between conflicting properties while reducing the need for costly and time-consuming experimental studies. Improvement of composite properties by substituting conventional matrix materials by high entropy alloys has recently been demonstrated with cemented carbides for friction stir welding, highlighting the potential of utilizing novel alloying concepts for MMC design. Here we present the current status of a hollistic ICME framework combining thermodynamic, kinetic and physics-based material models, which not only allows for further improvement of existing materials for well-established applications but also enables rapid exploration and design of other types of MMCs for a wider range of applications than presently used. |
