Project target

The main project target of development of scientific principles and technological basis of obtaining advanced light Al based composite materials, dopes with Mg, Ti, Cu and Ni, containing chemically and structurally modified BN nanostructures to achieve unique mechanical characteristics.

Project objectives

- Nano-BN surface modification with plasma processing

- Studying chemical connection between metallic matrix and modified BN phase by methods of infrared and Raman spectroscopy

- Studying  BN plasma modified surface morphology by methods of atomic-powered microscopy, scanning and transmission electronic microscopy

- Obtaining Al based and Mg, Ni, Cu and Ti doped composite materials, reinforces with plasma modified nanotubes and BN nanoparticles by methods of powder metallurgy (plasma pulse-discharge sintering and high-pressure torsion) and melt spinning

- Mechanical test of composites compression – pulling test at room and high (500 oC) temperatures

- Comparison of the received results with composite materials without plasma-modified nanophase.

- Studying damping properties of composites based on Al matrix, doped with Mg, Ti, Cu and Ni, and reinforced by BN nanophase in various structural states (after sintering, deformation, annealing) under cyclic load in the interval of normal and higher temperatures

- Studying processes of implanting various metals ions on the surface of BN nanophases of different morphology.

-Development of composites theoretical models and forecast of their mechanical properties. 

Uniqueness project

Development, obtaining and optimization of ultrastrong composite material structure based on light metallic matrix and NB nano structures with controlled nanophase/ metallic matrix border. BN nano structures reinforcement of metallic matrix provides for multi-fold increase of hardness, ultimate resistance and elastic strength of composite materials in wide temperature range compared to non-reinforced metals and alloys.

Chemical and structural modification of BN nanostructures surfaces will provide for better wettability of metallic matrix and formation of firm metal/BN interface. It will provide for even load transmission under various deformations and consequently will lead to multi-fold Al matrix reinforcement (including Mg, Ti, Cu and Ni alloys).We will develop advanced approaches to modelling NB nanostructure modification processes.

An important part of the project is studying mechanical behavior of new composite materials under various load conditions (compression, pulling, three-point bending, and applied dynamic shock) as well as high temperatures similar to real operation temperatures in aviation, automobile and space industries.
