Design and modelling of metal matrix composites

"Metal matrix composites (MMCs) reinforced with submicron ceramic particles have been objective of many research studies due to their excellent properties and the possibility to adequately respond to demanding operating conditions in various industries. The copper matrix composites (CuMMs) possess unique electrical and thermal conductivity, wear and corrosion resistance, and mechanical properties showing the broad potential applications in industries such as automotive, aerospace, nuclear, shipbuilding, etc. Hence, the design, investigation, and manufacturing of the CuMMs attract both researchers and engineers from various fields. Therefore, in the past decades, great attention is given to the selection of the manufacturing techniques, which will lead to the production of CuMCs with excellent (and desirable) properties. It is well known that the properties of MMCs strongly depend on the reinforcements' nature and distribution. Additionally, by manipulating the process parameters, the control on the reinforcements' distribution can be achieved. On the other hand, optimization of production parameters is usually a very time-consuming and costly process that encourages the development of computational models. The Marie Skłodowska Curie Action (MSCA) project titled ""DeMoMet: Design and modelling of metal matrix composites"" consists of experimental and computational work. The overall objectives of the DeMoMet project are to establish a computational model for the mechanical alloying process and optimizing parameters for the production of MMCs and to expand the knowledge related to relations between metal matrix composite (MMC) production parameters and their mechanical properties. The research conducted during the fellowship contributes to a better understanding of the particle behavior inside the mill as well as the influence of the milling parameters on the final material properties after the densification. All objectives, activities, and deliverables proposed in the MSCA application have been fully accomplished."

Цел на проекта

Excellent mechanical properties make metal matrix composites (MMCs) an attractive and desirable material in many industries. However, manufacturing costs of MMCs are currently very high mainly due to lack of material design database and limited knowledge related to their behavior in various working conditions. This proposed research aims to improve understanding of the relation between MMCs production parameters and their properties. The proposed research plan has two main assignments: firstly, to experimentally obtain optimal processing parameters for producing highly conductive, strengthened copper matrix composites with uniform dispersion of submicron and nano-sized reinforcements; secondly, to create a computational model for mechanical alloying process and for predicting the behaviour of MMCs. Powder metallurgy will be used for MMCs production. It is expected that with increasing mechanical alloying time the distribution of reinforcements (in-situ formed during densification process) in metal matrix become more uniform which is a requirement for excellent mechanical properties. Investigating the influence of size and volume fraction of in-situ formed reinforcing nanoparticles on its microstructural, mechanical and physical properties will be the overall objective of the experimental work. Proposed techniques, data collection, and analysis will identify the relationship between process parameters and material behaviour, which will contribute to the establishment of process parameters for fabrication of MMCs. Obtained results will present a good database which can accelerate further research, development and possible implementation of MMCs. Moreover, creating computational models for control of microstructure and process design of MMCs will contribute to a better understanding and predicting the behaviour of a wide variety of MMCs. It will provide a cost effective solution in the manufacturing of MMCs which will expand possibilities in the design of new products.
