Development of fundamental principles of creation of composite materials on the basis of aluminum alloys with the use of nanoquasicrystalline reinforcing particles, studying of their physical bases of strength.
popup.description2
The object of research is composite materials on Al-Fe-Cr alloys based, which contain quasicrystalline and crystalline phases and obtained by water-atomization technique.
The purpose of the research is develop the fundamental principles of obtaining and studying the deformation processes of aluminum alloys for elevated temperatures application.
Research methods are microhardness measurements, mechanical tensile tests, tribological tests, scanning and transmission electron microscopy, Xray diffraction analysis.
Optimal chemical compositions of Al-Fe-Cr alloys with microalloying by number of transition metals are selected. These alloys are aluminum matrix composites in which the solid aluminum solution is reinforced with nanosized particles of quasicrystals and / or intermetallics. It is proved that due to the fact that nanostructured quasicrystals, in contrast to coarse-grained, have some plasticity at room temperature, the nanoquasicrystals are well applicable for strengthening of aluminomatrix composites for a operation at temperatures up to 300 °C.
