| description | Our work deals with the problem of producing a complex metal-ceramic
composite using the processes of internal oxidation (IO) and severe plastic
deformation. For this purpose, Cu-Al alloy with 0.4wt.% of Al was used. IO of
sample serves in the first step of the processing as a means for attaining a
fine dispersion of nanosized oxide particles in the metal matrix. Production
technology continues with repeated application of severe plastic deformation
(SPD) of the resulting metalmatrix composite to produce the bulk nanoscaled
structural material. SPD was carried out with equal channel angular pressing
(ECAP), which allowed that the material could be subjected to an intense
plastic strain through simple shear. Microstructural characteristics of one
phase and multiphase material was studied on internally oxidized Cu with
0.4wt.% of Al sample composed of one phase copper-aluminum solid solution in
the core and fine dispersed oxide particles in the same matrix in the mantle
region. In this manner AFM, X-ray diffraction and Raman spectroscopy were
used. Local structures in plastically deformed samples reflect presence of
Cu, CuO, Cu2O, Cu4O3 or Al2O3 structural characteristics, depending on type
of sample. [Projekat Ministarstva nauke Republike Srbije, br. III45003] |
